i want to post name email and comment from front end .. wasted almost 2 days without no success.. please help..

since you are passing the data manually from html rewrite this function
if comment_form.is_valid():
content = request.POST.get('content', '')
email = request.POST.get('email', '')
name = request.POST.get('author', '')
comment =Comment.objects.create(post= blg, email=email, name=name, content=content)
return redirect('posts-detail', pk=comment.id )<this can be how you like it>
what you are missing is getting the missing fields in html they are taken from name attribute in the input

if comment_form.is_valid():
content = request.POST.get('content')
Comment.objects.create(post= blg , content=content) # YOU HAVE ADDED post= post even post variable you are not define
comment_form.save()

How to redirect to a form after parsing an uploaded csv file if items don't exist in database?

I am having an issue that i have been trying to solve for a few days and feel like I have hit a roadblock and can't find the answers I need. What I am trying to do is:
Upload a csv file (this file basically contains details about stock trades) which will be saved in a table and stored in media directory, the content is then parsed and passed to a dictionary (this step is working) -- the contents of this file will be used to update various tables in my database later.
As I loop through the key, value pairs in the dictionary check to see if certain values exist in various models which are used as foreign keys (this part also works) -- So for example, if a trade is tagged with Fund X and fund X doesn't exist in my Fund table, it will take me to a form to fill in all the required fields to create fund X in my database
If a value is missing I want to be sent to a form that will then allow me to create this value in the database so that I can populate the required fields (this part is partially working, I can get to the form for missing data but I am unable to save the inputs of that form to the data base)
I have a utils.py file that will be containing all of my classes or helper functions to accomplish this.
if i print out fund_form.errors in from my views.py file i get the following:
<ul class="errorlist"><li>fund_code<ul class="errorlist"><li>This field is required.</li></ul></li><li>fund_name<ul class="errorlist"><li>This field is required.</li></ul></li></ul>
Please let me know if you need any other information I have been struggling with this for a few days.

Trying to edit a form using django and python

I'm trying to edit the form via my edit button.
When i click update button in my form I'm getting the following error:
FieldError at /studentapp/editrow/72/
Cannot resolve keyword 'rowid' into field Choices are: address, course, id, name, pub_date, roll
My traceback shows the error originating in this line
item = get_object_or_404(Studentapp, rowid=id) this line.
My models.py looks like this:
class Studentapp(models.Model):
name = models.CharField(max_length=100)
roll = models.IntegerField()
course = models.CharField(max_length=100)
address = models.CharField(max_length=100)
pub_date = models.DateTimeField('date published', auto_now=True)
def __str__(self):
return '%s %s %s %s' % (self.name, self.roll, self.course, self.address)
def published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
EDIT
My view:
def editrow(request, id):
item = get_object_or_404(Studentapp, id=id)
if request.method=="POST":
form = EntryForm(request.POST, instance=item)
if form.is_valid():
post=form.save(commit=False)
post.save()
return HttpResponseRedirect(reverse('studentapp:index'), id)
else:
form=EntryForm(instance=item)
return render(request, 'index.html',{'form':form})
else:
form=EntryForm(instance=item)
return render(request, 'index.html',{'form':form})
My urls.py
url(r'^editrow/(?P<rowid>[0-9]+)/$', views.editrow, name='editrow'),
Form that i'm using to update the entry:
{% load staticfiles %}
<form action="{% url 'studentapp:editrow' student_detail.id %}" id="editform" method="POST">
{% csrf_token%}
<div class = "form-group">
<label for = "your_name">
Your name:
</label>
<input class = "form-control" id="new_name" type = "text" name="name" value="{{ student_detail.name }}" placeholder="Enter your name">
</div>
<div class="form-group">
<label for = "course_name">
Course:
</label>
<input id="new_course" class = 'form-control' type = "text" name="course" value="{{ student_detail.course }}" placeholder="Enter your course">
</div>
<div class = "form-group">
<label for = "rollno">
Roll No.:
</label>
<input id="new_rollno" type = "text" class = 'form-control' name="roll" value="{{ student_detail.roll }}" placeholder="Enter your roll number">
</div>
<div class = "form-group">
<label for ="addr">
Address:
</label>
<input id="new_address" type = "text" name="address" class = 'form-control' value="{{ student_detail.address }}" placeholder="Enter your address"/>
</div>
<input type = "submit" value="Update" id="update" class = "btn btn-success" style="font-size:18px;" />
</form>

This line is not right, your model does not have the field rowid
item = get_object_or_404(Studentapp, rowid=id) this line. # WRONG
item = get_object_or_404(Studentapp, id=id) this line. # OK
and your urls should be
url(r'^editrow/(?P<id>[0-9]+)/$', views.editrow, name='editrow'),
# url(r'^editrow/(?P<rowid>[0-9]+)/$', views.editrow, name='editrow'), # WRONG

set a Boolean when submitted in django

I want to set a Boolean field is_rep in a retest model to true when the retest form is submitted.
Now it is just get added up in a retest model.
Because I want to trigger other events when the request is submitted.
My code
models.py
class Retest(models.Model):
semester = models.ForeignKey(Semester)
dept = models.ForeignKey(Departement)
batch = models.ForeignKey(Batch)
date = models.DateField(default=0)
subject = models.ForeignKey(Subject)
name = models.CharField(max_length=50)
admnno = models.CharField(max_length=50)
reason = models.CharField(max_length=50)
proof = models.CharField(max_length=200)
is_hod = models.BooleanField(default=False)
is_principal = models.BooleanField(default=False)
notify = models.BooleanField(default=False)
is_sure = models.BooleanField(default=False)
is_rep = models.BooleanField(default=False)
def get_absolute_url(self):
return reverse( 'retest:retestform')
def __str__(self):
return self.name
urls.py
url(r'^retest/retestform/$',login_required(views.RetestCreate.as_view()), name='retestform')
views.py
class RetestCreate(CreateView):
model = Retest
fields = ['semester', 'dept', 'batch', 'date', 'subject', 'name', 'admnno', 'reason', 'proof', 'is_sure']
template
<form class="form_horizontal" action="" method="post" enctype="multipart/form-data" >
{% csrf_token %}
{% include 'retest/form-template.html' %}
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-success">Submit</button>
</div>
</div>
</form>

If you want to set the boolean field to true, when the form is submitted, you just have to handle it in the view.
Submit the form and before saving it into the database just set the is_rep = true.
is_rep is a field which is in the model, but not used in the form.
So, if you want to change that then you have to manually write a view for it. Try to use base view instead of generic views to understand the workflow of the views and forms.
I'd recommend using something like this:
class RetestView(View):
def get(self, request, *args, **kwargs):
..............
return render(request, self.template, {"some_context"}
def post(self, request, *args, **kwargs):
form_data = your_form(request.POST)
if form_data.is_valid():
new_object = form_data.save(commit=False)
new_object.is_rep = True
new_object.save()
return render(request, self.template, {"some...context"})
Hope you got what you were looking for..!

form_template
{% for field in form %}
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<span class="text-danger small">{{ field.errors }} </span>
</div>
<label class="control-label col-sm-2">{{ field.label_tag }} </label>
<div class ="col-sm-12">
<div class="form-control">
{{ field }}</div></div>
</div>
{% endfor %}

django template form not saving data

I have a template form and trying to save some data. Upon clicking on the submit button the page just refreshes and nothing gets saved to the database. I don't get any errors on anything.

<form action="" method="post" id="salesform">
{% csrf_token %}

<input type="email" class="form-control" id="email" placeholder="Email">
<button id="sub" type="submit" class="btn btn-default">Submit</button>
</form>
forms.py
class LeadForm(forms.ModelForm):
name = forms.CharField(max_length=250, required= True,widget=forms.TextInput())
clinic_name = forms.CharField(max_length=250, required= True,widget=forms.TextInput())
phone = forms.CharField(max_length=8, required= True,widget=forms.TextInput(attrs={'type':'number'}))
email = forms.CharField(max_length=250, required= False, widget=forms.TextInput())
class Meta:
model = Lead
fields = ("clinic_name","phone")
views.py
def add_doc_info(request):
d = getVariables(request,dictionary={'page_name': "Doctors",
'meta_desc' : "Sign up "})
if request.method == "POST":
SalesForm = LeadForm(request.POST)
if SalesForm.is_valid():
name = SalesForm.cleaned_data['name']
clinic_name = SalesForm.cleaned_data['clinic_name']
phone = SalesForm.cleaned_data['phone']
email = SalesForm.cleaned_data['email']
#Saving to database
lead = Lead(name=name, clinic_name=clinic_name, phone=phone, email=email)
lead.save()
else:
SalesForm = LeadForm()
return render(request, 'm1/add_doc_info.html', d, context_instance=RequestContext(request))
models.py
class Lead(models.Model):
name = models.CharField(max_length=1300)
clinic_name = models.CharField(max_length=1300)
phone = models.IntegerField()
email = models.EmailField(blank = True)
submitted_on = models.DateField(auto_now_add=True)
def __unicode__(self):
return u"%s %s" % (self.clinic_name, self.phone)

Almost certainly the form is not valid, but you're not using it in your template so there is no way for it to display errors, or redisplay itself with partially-filled fields.
The Django documentation is fairly explicit on this, so I don't know why you have done something different. Pass the form into your context:
d['form'] = SalesForm
return render(request, 'm1/add_doc_info.html', d)
and use it in the template:
{{ form.errors }}
<form action="" method="post" id="salesform">
{% csrf_token %}
{{ form.name }}
{{ form.clinic_name }}
{{ form.phone }}
{{ form.email }}
<button id="sub" type="submit" class="btn btn-default">Submit</button>
</form>
(Note also you've unnecessarily defined all the fields explicitly in the form, but also stated you are only using two of them in the meta class; also your is_valid block is mostly unnecessary as you can just call form.save() directly. Again, all this is shown fully in the documentation.)
