WTForms Field shows up when run, but has Unbound problems

I'm new to Flask and JS, so I'm really not sure what the problem is here.
app.py
#app.route('/email', methods=["GET", "POST"])
def email():
email_form = EmailForm(csrf_enabled=False)
return render_template("email-form.html", template_form=email_form, action='/appliance2', method='POST')
forms.py (I created that validator using the template from the wtForms docs)
class DBPresenceCheck(object):
def __init__(self, table, message="Field is invalid"):
self.table = table
self.message = message
def __call__(self, form, field):
presence = Connector().query('SELECT 1 FROM %(table)s WHERE %(col_name)s = %(data)s LIMIT 1;',
{'col_name': field.label, 'data': field.data, 'table': self.table})
if presence == 1:
raise ValidationError(self.message)
class EmailForm(FlaskForm):
title = "Enter Household Info"
subtitle = "Please enter your email address:"
email_input = StringField("email", validators=[email(),
DBPresenceCheck('Household', 'That email is already present in the database.')])
# print(email_input.data)
submit = SubmitField("Submit")
email-form.html
{% extends "base.html" %}
{% block content%}
<div class="container py-4">
<div class="p-5 mb-4 bg-light rounded-3">
<h2 class="display-5 fw-bold">{{ template_form.title }}</h2>
<p class="col-md-8 fs-4">{{ template_form.subtitle }}</p>
<form action="{{ action }}" method="{{ method }}">
<div id="main_elements">
{{ template_form['email_input']() }}
</div>
<div id="submit_element">
<br>
{{ template_form["submit"](class_="btn btn-primary") }}
</div>
</form>
</div>
</div>
{%endblock%}
I first realized something was wrong when I was testing the validation, and neither validator ever threw. I added the print statement in forms, and now, when I use flask run, I get the following error.

AttributeError: 'UnboundField' object has no attribute 'data'
If the print statement is just print(email_input), then when I run it, the following output
<UnboundField(StringField, ('email',), {'validators': [<wtforms.validators.Email object at 0x0000024145A4F460>, <forms.DBPresenceCheck object at 0x0000024145A4F610>]})>
but no errors are thrown. It seems strange to me that the error is thrown before the field is even created.

In the validators list you need to pass in an instance of class Email. So you field should read:
from wtforms.validators import Email
email_input = StringField("email", validators=[Email(), ...
and don't forget to install the email package as Flask-WTF doesn't include anymore the Email in their validators.

AttributeError: type object 'Project' has no attribute '_meta'

I encountered the following in my Django files when I attempt to use the class based view CreateView.
AttributeError at /overview/new/
type object 'Project' has no attribute '_meta'
I have no idea why the _meta attribute is not there. I inherited my model from models.Model as usual, but I can't find any questions that have the same problem. I posted my files down below, can somebody help me fix this problem?

From your URLs, it looks like you have a view Project which is clashing with the model Project.
path('project/<pk>/', login_required(views.Project.as_view()), name='projects-project'),
The simplest fix would be to rename that view, for example to ProjectDetail, and update the URL pattern.

TypeError: 'NoneType' object is not subscriptable followed by AttributeError: 'NoneType' object has no attribute 'split'

Using django. I have the following model:
class Postagem(models.Model):
id = models.AutoField(primary_key=True, editable=False)
descricao = models.CharField(max_length=50)
area = models.ForeignKey('core.Area', null=True)
user = models.ForeignKey('User')
categoria = models.CharField(max_length=50, null=True)
post = models.FileField(upload_to='posts/', null=True)
thumbnail = models.FileField(upload_to='posts/', null=True)
def __str__(self):
return self.descricao
The Following form:
class PostForm(forms.ModelForm):
categoria = forms.ChoiceField(choices=[("Video","Vídeo"),("Audio","Aúdio"),("Imagem","Imagem"),("Musica","Música")], required=True)
thumbnail = forms.FileField(required=False)
class Meta:
model = Postagem
fields = ['descricao', 'area', 'user', 'post']
View:
def profileView(request):
context = getUserContext(request)
if request.method == 'POST':
exception=None
userDict = {}
userDict["user"] = context["user"].id
if "categoria" in request.POST:
newPost = request.POST.copy()
newPost.update(userDict)
form = PostForm(newPost,request.FILES)
print("postform POST: ",newPost, " File ",request.FILES)
if form.is_valid():
print("valid")
try:
form.save()
print("saved")
return HttpResponseRedirect(reverse_lazy('accounts:profile'))
except IntegrityError as e:
print("Integrity Error")
exception=e
else:
print("PostForm error")
print(form.errors)
form.non_field_errors=form.errors
if exception is not None:
form.non_field_errors.update(exception)
context['form']=form
posts = Postagem.objects.get_queryset().order_by('id')
paginator = Paginator(posts, 12)
page = request.GET.get('page')
context["areas"] = Area.objects.all()
try:
posts = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
posts = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
posts = paginator.page(paginator.num_pages)
context["posts"]=posts
return render(
request,
'accounts/profile.html',
context
)
And at last the template:
{% for post in posts %}
{% if forloop.counter0|divisibleby:4 or forloop.counter0 == 0 %}
<div id="grid-profile" class="row grid">
<div class="col-md-1"></div>
{% endif %}
{% ifnotequal post.categoria "Imagem"%}
<iframe id=post{{forloop.counter}} width="420" height="315"
src={{post.post.url}}>
</iframe>
{% else %}
<div class="col-md-2">
<button type="button" id="modal1trigger" data-toggle="modal" data-target="#modal1"><img class="img-responsive" src={{post.post.url}}></img></button>
</div>
{% endifnotequal %}
{% if forloop.counter|divisibleby:4 or forloop.counter == posts|length %}
<div class="col-md-1"></div>
</div>
{% endif %}
{% endfor %}
<div class="pagination">
<span class="step-links">
{% if posts.has_previous %}
previous
{% endif %}
<span class="current">
Page {{ posts.number }} of {{ posts.paginator.num_pages }}.
</span>
{% if posts.has_next %}
next
{% endif %}
</span>
</div>
I cut some of the template... Anyways, I want to be able to add all kinds of posts. Songs, Videos, Images, Docs, etc. And it IS working. The posts are being added. But, I'm having a recurring error and I don't know why. That could be very dangerous so I started looking into it, but with no luck in finding an acceptable answer. The error only happens when trying to get a song or a video.

Edit:
Using Django 1.11.3,
Windows 10,
Tested with Opera and Chrome,
Running server using gulp
**Edit 2: **
Hey, the error ONLY HAPPENS if there is a iframe tag in the html!!

It appears that its a python error:
Django ticket: https://code.djangoproject.com/ticket/26995
Python ticket: https://bugs.python.org/issue14574
Didn't managed to solve just yet, if I can I will edit this answer explaining in detail how to solve it.
Edit
It seems to be a error on chrome. It didn't come to me, 'cause I was using Opera, but opera uses chromium as well. In internet explorer the error didn't show.
https://code.djangoproject.com/ticket/21227#no1

self.environ['SERVER_PROTOCOL'].upper() is failing because self.environ['SERVER_PROTOCOL'] is None, and you can't do None.upper() you can only do .upper() on strings (as far as i'm aware).
the second error
self.status.split(' ',1)[0], self.bytes_sent
AttributeError: 'NoneType' object has no attribute 'split'
This is failing because you self.status is None and you can't do None.split(), again this should be a string.
So it looks like some of the required values for these classes aren't being initialised or passed through.
It looks like the issue is with Django.core and WSGIref, so either the configuration isn't correct or perhaps there's an issue with the version you have installed?
Which version of Django are you running?
Also are you running the server from ./manage.py runserver ?
[update 2017-09-28]
There's a couple of things I've modified, to start with I'm not copying the request.POST to a new dict, before passing it, this could be the cause of some of the values disappearing when trying to process a post.
I'm also passing user as a kwarg to your form, rather than trying to inject it into the copied POST.
mostly I've just updated some of the code to be a little easier to read, let's see how that goes.
# forms.py
class PostForm(forms.ModelForm):
categoria = forms.ChoiceField(choices=[("Video","Vídeo"),("Audio","Aúdio"),("Imagem","Imagem"),("Musica","Música")], required=True)
thumbnail = forms.FileField(required=False)
class Meta:
model = Postagem
fields = ['descricao', 'area', 'user', 'post']
def __init__(self, *args, **kwargs): # handle user kwarg
if 'user' in kwargs.keys():
self.user = kwargs.pop('user')
super(PostForm, self).__init__(*args, **kwargs)
# views.py
def profileView(request):
form = None
if request.method == 'POST':
exception=None
if "categoria" in request.POST:
if request.user:
form = PostForm(request.POST,request.FILES, user=request.user) # pass user as a kwarg
print("postform POST: ",newPost, " File ",request.FILES)
if form.is_valid():
print("valid")
try:
form.save()
print("saved")
return HttpResponseRedirect(reverse_lazy('accounts:profile'))
except IntegrityError as e:
print("Integrity Error")
exception=e
else:
print("PostForm error")
print(form.errors)
#form has been indented as previously it would have been called before being initialised
form.non_field_errors=form.errors
if exception is not None:
form.non_field_errors.update(exception)
posts = Postagem.objects.get_queryset().order_by('id')
paginator = Paginator(posts, 12)
page = None
if request.GET:
page = request.GET.get('page')
areas = Area.objects.all()
try:
posts = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
posts = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
posts = paginator.page(paginator.num_pages)
#return values
return render(
request,
'accounts/profile.html',
{
'form': form,
'areas': areas,
'posts': posts,
}
)

BadValueError: Property text is required

I've done a lot of research trying to solve this problem myself but I am running up short of a solution. If anyone can give me any pointer or help I would really appreciate it.
I am creating a blog that has basic blog functionality such as; likes, dislikes, posts, comments, multiple users, CRUD functions etc. I have so far been able to overcome most of my problems and I am near the completion of this project.
The last bit of trouble I am having is with my Edit Comment functionality, I can delete a comment just fine but if I try to update a comment I got the following error:

Now I am not exactly sure why this is happening, I looked up the solutions that others were finding for similar problems and none seemed to apply to my situation. Here is my relevant code for reference:
EditComment(BlogHandler)

def get(self, post_id, comment_id):
post = Post.get_by_id(int(post_id), parent=blog_key())
comment = Comment.get_by_id(int(comment_id))
if comment:
if comment.user.name == self.user.name:
self.render("editcomment.html", comment_text=comment.text)
else:
error = "You may only edit your own comments"
self.render("editcomment.html", edit_error=error)
else:
error = "This comment no longer exists"
self.render("editcomment.html", edit_error=error)
def post(self, post_id, comment_id):
if self.request.get("update_comment"):
comment = Comment.get_by_id(int(comment_id))
if comment.user.name == self.user.name:
comment.text = self.request.get('comment_text')
comment.put()
time.sleep(0.1)
self.redirect('/post/%s' % str(post_id))
else:
error = "you may only edit your own comments"
self.render(
"editcomment.html",
comment_text=comment.text,
edit_error=error)
elif self.request.get("cancel"):
self.redirect('/post/%s' % str(post_id))
Comment(db.model)
class Comment(db.Model):
user = db.ReferenceProperty(User, required=True)
post = db.ReferenceProperty(Post, required=True)

#classmethod

Now the traceback does not point to the area in my code that is causing the issue so I will provide the relevant lines of the __inti__.py file here:
Line 617
def __set__(self, model_instance, value):
"""Sets the value for this property on the given model instance.
See http://docs.python.org/ref/descriptors.html for a description of
the arguments to this class and what they mean.
"""
value = self.validate(value)
setattr(model_instance, self._attr_name(), value)
Line 2810
raise BadValueError('Property %s must be convertible '
'to a %s instance (%s)' %
(self.name, self.data_type.__name__, err))
value = super(UnindexedProperty, self).validate(value)
if value is not None and not isinstance(value, self.data_type):
raise BadValueError('Property %s must be a %s instance' %
(self.name, self.data_type.__name__))
return value
Line 644
if self.empty(value):
if self.required:
raise BadValueError('Property %s is required' % self.name)
I'm not sure what I'm doing wrong here, and if anyone would be able to offer me any kind of advice I would be very grateful. Thanks again

The error indicates that the value you get from self.request.get('comment_text') and pass to comment.text is invalid - None probably.
The check is done because the text property has the option required set to True in the Comment model.
So check that you properly pass the 'comment_text' request parameter (or its value) around.
Maybe you need name="comment_text" in the following line from editcomment.html?
<textarea class="u-full-width" name="text" id="texta2">{{comment_text}}</textarea>

keyError in Django. During template rendering

Sorry if its a noob code or question. I am doing pagination using django-pagination and I am doing it like this.But this gives me keyError at on my page furthermore it mentions that its an error during template rendering. What I am doing wrong here.I have successfully installed pagination, modified the settings.py file. But i dont know what i need to do here. Any help would be highly appreciated.
<table class="active_table" summary="active_user">
<thead>
<tr><th>Name</th><th>Mobile Number</th><th>Count</th></tr>

{% load pagination_tags %}

{% autopaginate response_data 5 %}
{% for b in response_data %}
<tr class="table_rows"><td>{{ b.name }}</td><td>{{ b.mobile_number }}</td><td>{{ b.count }}</td></tr>
{% endfor %}
{% paginate %}

Sorry I am not using django ORM as of now but I will do so in future.

You must add context_instance in render_to_response call:
return render_to_response("siteadmin/active_user_table.tmpl",{'response_data': response_data}, context_instance=RequestContext(request))
or you can use TEMPLATE_CONTEXT_PROCESSORS tuple in your settings.py. Add this string "django.core.context_processors.request" to context processors and every RequestContext will contain a variable request.

I solved it myself but thanks to ndpu for helping me atleast I got confident there were no other issue but some settings issue. In this question I have problems with setting up django-pagination. Alasdair had mentioned adding "django.contrib.auth.context_processors.auth", to TEMPLATE_CONTEXT_PROCESSORS . On just adding it I am getting the correct expected values.

For those who are using the render shortcut
and still facing this error, just add {'request': request } to the context variable
context = { ..., 'request':request}
return render(request, 'templatename.html', context)

I also face this error earlier. I was getting following error:

I tried some google solutions but couldn't resolved, then finally again check my code and found a silly mistake on template file.
Just add:
{% load static %}
on top of your template file.
