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>
</thead>
<tbody id="table_content">
{% load pagination_tags %}
{% block content %}
{% 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 %}
{% endblock %}
</tbody>
</table>
The detailed traceback is pasted here http://dpaste.com/919526/
The viewcode is following
views.py

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.

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")

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.

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.
I have written an flask app.
This app allow users to upload images, if i run this app locally this app uploads images and saves it to the path which i have designated
Now i want to create a query string for my app where i will create urls and send it to people to upload images.
but when i run my app i receive this error
werkzeug.routing.BuildError: Could not build url for endpoint 'index'. Did you forget to specify values ['property_id']?

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.
You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:
dump() shows all variables in the frame
dump(obj) dumps all that's known about the object

I have read this posts:
werkzeug.routing.BuildError: Could not build url for endpoint 'success'. Did you forget to specify values ['name']?
How do you get a query string on Flask?
werkzeug.routing.BuildError: Could not build url for endpoint
render_template('index.html', property_id= property_id)
Your index.html does not use property_id. You can discard the property_id argument if index.html indeed do not need it
in index.html, line 14
dropzone.create(action_view='index')
action_url = url_for(action_view, **kwargs)
the later url_for would invoke index() method again, but missed the argument property_id, and moreover it seemed that you are making a recursive call!
I have 2 question cause little bit comfused with django-reversion app. I have page where users can see list all of reversions. Every version has button to revert.
1 Question: How to show only some fields of changes. Right now it shows me all fields. I use version.field_dict.items.
2 Question: How to make correct revert to specific version?
Here below you can see code but it raise Error in views.py when I try to click to revert link. What I did wrong?
template.html
{% for version in versions %}
{% for field_name, field_value in version.field_dict.items %}
{{ field_name }}
{{ field_value }}
{% endfor %}
REVERT
{% endfor %}
urls.py:
url(r'^(?P<project_code>[0-9a-f-]+)/(?P<group_code>[0-9a-f-]+)/(?P<group_reversion_id>\d+)/$',
group_revert,
name='group_revert'),
views.py:
def group_revert(request, project_code, group_code, group_reversion_id):
project = get_object_or_404(Project, pk=project_code, status='open')
group = get_object_or_404(Group, pk=group_code)
versions = Version.objects.get_for_object(group)
versions[group_reversion_id].revision.revert()
return redirect('project:project_detail', project_code=project.code)

I found the answer to this question: dhango-reversion
I'm trying to make a flask app on google app engine which shows database entries on their own page.
This is a bit of my views.py code:
#app.route('/posts/<int:id>')
def display_post(id):
post = Post.filter('id =', id)
return render_template('display_post.html', post=post)
Then my display_posts.html
{% extends "base.html" %}
{% block content %}
<ul>
<h1 id="">Post</h1>
<li>
{{ posts.title }}<br />
{{ posts.content }}
</li>
</ul>
{% endblock %}
Now when I have a post with ID 5700305828184064 and visit this page I should see the title and content:
www.url.com/posts/5700305828184064
However I get this traceback:
<type 'exceptions.AttributeError'>: type object 'Post' has no attribute 'filter'

How can I show the title and content of the entry for a given ID?
You need to create a query object first, then apply the filter to that.
q = Post.all()
post = q.filter("id =", id)
This is the first example in the GAE docs on queries.
Also, your template references the name posts, but you've passed in the name post. Change your template appropriately.
