I have the following model:
class Portfolio(models.Model):
id = models.AutoField(primary_key=True)
member = models.ForeignKey(Member, on_delete=models.CASCADE)
image = models.ImageField(upload_to='portraits/', default='/images/some_image.png')
For that I made the ModelForm:
class PortfolioForm(forms.ModelForm):
class Meta:
model = Portfolio
exclude = ['id']
I need many of those in one template so I am creating them in the Following way in my view
def portfolio_form(request, pk):
...
formset = PortfolioFormSet(queryset=Portfolio.objects.filter(pk__in=list_of_ids))
for x in p]
finally in the html I have this:
<form enctype="multipart/form-data" action="{% url 'elec:portfolio_form' pk=id %}" method="POST">{% csrf_token %}
...
{{ formset.management_form }}
{% for form in formset.forms %}
<tr>{% for field in form %}
{% if field.name == 'image' %}
<td><img src="{{field.image.url}}"></td>
{% else %}
<td align="center" valign="middle">{{field}}</td>
{% endif %}
{% endfor %}</tr>
{% endfor %}
<input type="submit" class="btn btn-default" value="Save and Refresh" />
</form>
Now what I expect to see is the image that I am saving into that Model. The if statement is coming back as false but why?. What am I doing wrong? Everywhere I looked it should work like this.
Also I have added the request.FILES in PortfolioForm with that the instance is not called how can I fix that?
OK I found the solution in Stackoverflow since I used some other words to find a solution.
what you need to do in the template instead of :
{<td><img src="{{field.image.url}}"></td>}
is this :
{<td><img src="{{form.instance.image.url}}"></td>}

I have created a model Announcement in models.py file
class Announcement(models.Model):
title = models.CharField(max_length=30)
content = models.TextField()
date_posted = models.DateTimeField(default=timezone.now)
teacher = models.ForeignKey(Teacher, on_delete=models.CASCADE)
def __str__(self):
return self.title
And for deleting a record of Announcement I have created the following view
def AnnouncementDelete(request, pk):
announcement = get_object_or_404(Announcement, pk=pk)
if request.method=='POST':
announcement.delete()
return redirect('/')
return render(request, 'classroom/announcement_confirm_delete.html', {'announcement': announcement})
The delete view of announcement (that is AnnouncementDelete) has the following url
path("delete/<int:pk>/", view=views.AnnouncementDelete, name="AnnouncementDelete"),
If i enter
http://127.0.0.1:8000/classroom/delete/3
on browser it is deleting the Announcement having pk = 3
Now I want a button to directly delete my record without the need of typing http://127.0.0.1:8000/classroom/delete/3 on browser
I have tried the following methods in my allannouncement.html file
{% extends "classroom/base.html" %}
{% block content %}
<h1>Announcements</h1>
{% for announcement in announcements %}
<!-- starting loop (posts is keyword from view) -->
<div style="border-style: solid;">
{% if announcement.teacher.user == request.user %}
<div>
Delete
</div>
{% endif %}
{{ announcement.pk }}
<a class="mr-2">Posted by: {{ announcement.teacher }}</a>
<h2><a class="article-title">{{ announcement.title }}</a></h2>
<p class="article-content">{{ announcement.content}}</p>
</div>
{% endfor %}
{% endblock content %}
but it is giving the following error
NoReverseMatch at /classroom/allannouncement/
Reverse for 'AnnouncementDelete' with no arguments not found. 1 pattern(s) tried: ['classroom/delete/(?P<pk>[0-9]+)/$']
then I also tried passing pk with url like
Delete
But it is giving the following error
TemplateSyntaxError at /classroom/allannouncement/
Could not parse the remainder: ',' from ','
Remove common #refer this
Delete
instead of a link add a form.
Add
{% load crispy_forms_tags %}
in your html file and then add
{% if announcement.teacher.user == request.user %}
<div>
<form action="{% url 'classroom:AnnouncementDelete' announcement.id %}"
method="post">
{% csrf_token %}
<input type="submit" value="Delete">
</form>
</div>
{% endif %}
I have the follow model:
class UserProfile(...):
...
photo1 = models.URLField()
photo2 = models.URLField()
photo3 = models.URLField()
photo4 = models.URLField()
photo5 = models.URLField()
And in the Create/Update template, I have to write five copies of the following div for file1 to file5:
<div>
Photo 1:
{% if userProfileForm.instance.file1 %}
<a href="{{ userProfileForm.instance.file1 }}" target=_blank>View</a>
{% endif %}
<input type=file name=file1>
{% if userProfileForm.instance.file1 %}
Delete
{% endif %}
</div>
Is there a way to iterate field file<i>?
{% for i in '12345' %}
<div>
Photo {{ forloop.counter }}:
...
</div>
{% endfor %}
in django you have _meta API. So I think this solves your problem if you use get_fields method (and maybe you will filter desired fields out).
hope it helps.
update with example
let me show how you should solve your problem:
desired_fields = []
for field in UserProfile._meta.get_fields()
if "photo" in field.name:
desired_fields.append(field.name)
context.update(fields=desired_fields) # pass it in the context
at this point you have your desired fields which should be used with for loop in the template. And one more thing, you would need to add some template tag to get real field from string representation:
# custom template tag
def from_string_to_field(instance, field_str):
return getattr(instance, field_str, None)
and in the template code will look like this
{% for field in fields %}
{{userProfileForm.instance|from_string_to_field:"field"}}
{% endfor %}
Hi guys,
I have this models:
class Pais(models.Model):
nome = models.CharField('Nome', max_length=50)
class Brinq(models.Model):
descricao = models.CharField('Nome', max_length=50)
class Filhos(models.Model):
nome = models.CharField('Nome', max_length=50)
idade = models.IntegerField('Idade')
pai = models.ForeignKey('Pais')
brinq = models.ForeignKey('Brinq', related_name='Brinq')
This view:
def editPai(request, idpai=None):
if idpai:
pai = Pais.objects.get(id=idpai)
else:
pai = None
ItensInlineFormSet = inlineformset_factory(Pais, Filhos, form=FilhosForm, extra=1)
formPais = PaisForm()
formsetItens = ItensInlineFormSet(instance=pai)
return render_to_response("base.html", {
"formPais": formPais, "formsetItens": formsetItens
}, context_instance=RequestContext(request), )
and this forms:
class PaisForm(ModelForm):
class Meta:
model = Pais
class FilhosForm(ModelForm):
class Meta:
model = Filhos
Ok, How can I get "descricao" value from "Brinq" model in my template? I think it's a simple question but, I tried looking, looking and looking again from internet and I don't find anything about this.
I start to thing it's not possible to do it using django, I want to believe that I'm wrong, but as I said, I didn't find anything about this in internet.
I try:
{% for form in formsetItens %}
<tr>
<td> {{ form.nome }}</td>
<td> {{ form.idade }}</td>
<td> {{ form.brinq__descricao }}</td>
</tr>
{% endfor %}
and {{ form.brinq.descricao}} to, and nothing... :(
Can anyone help me with this problem?
Regards,
You are trying to iterate over a FormSet. As the docs say "The formset gives you the ability to iterate over the forms in the formset and display them as you would with a regular form".
So you can for example do the following to display all the fields included in the form:
{% for form in formsetItens %}
{{ form.as_table }}
{% endfor %}
..or if it fits your use case you could wrap each form into a form tag, and loop over the form fields:
{% for form in formsetItens %}
<form action="/contact/" method="post">
{% for field in form %}
<div class="fieldWrapper">
{{ field.errors }}
{{ field.label_tag }} {{ field }}
</div>
{% endfor %}
<p><input type="submit" value="Send message" /></p>
</form>
{% endfor %}
(I'm quite new at django, i googled for this a lot but could not find an answer, so i hope you don't mind the low level question)
There are these Classes:
class Cl(models.Model):
user = models.ForeignKey(User,editable=False)
title = models.CharField(max_length=100)
class Member(models.Model):
name = models.CharField(max_length=100)
email = models.EmailField()
cl = models.ForeignKey(Cl)
class ClForm(ModelForm):
class Meta:
model = Cl
I want to make a page where i can create an Object of Cl and some related Member Objects (I plan to use django-dynamic-formset but that is not the point here). My view looks like this:
class NewView(TemplateView):
def get(self, request):
cform = ClForm(prefix="cl", instance=Cl(user=request.user))
MemberFormSet = modelformset_factory(Member)
memberfs = MemberFormSet(queryset=Member.objects.none())
return render_to_response(self.template_name, {'cl_form': cform, 'memberformset': memberfs}, context_instance=RequestContext(request))
def post(self,request):
cform = ClForm(request.POST, prefix="cl", instance=Cl(user=request.user))
MemberFormSet = modelformset_factory(Member)
memberfs = MemberFormSet(request.POST)
if cform.is_valid() and memberfs.is_valid():
new_cl = cform.save()
new_members = memberfs.save(commit=False)
for mf in new_members:
mf.cl = new_cl
mf.save()
return HttpResponseRedirect("unimportant")
return render_to_response(self.template_name, {'cl_form': cform, 'memberformset': memberfs}, context_instance=RequestContext(request))
My template looks like this:
<form id="myForm" method="post" action="">
{% csrf_token %}
{{ memberformset.management_form }}
<table>
{{ cl_form }}
<tr><th colspan="2">Members</th></tr>
{% with memberformset.empty_form as form %}
<div id="id_empty_form" style="display:none;">
{{ form }}
</div>
{% endwith %}
</table>
<input type="submit" value="Save" />
</form>
My problem is now, that the member is not stored. Also, the memberfs.is_valid() doens't complain, if e.g. the Email field is not filled out correctly.
I also tried the inlineformset_factory, but that didn't worked either.
I think the problem is that you are using the "empty_form" in that template. The correct way of using the formset is described here. In your example, you should write:
<form id="myForm" method="post" action="">
{% csrf_token %}
{{ memberformset.management_form }}
<table>
{{ cl_form }}
<tr><th colspan="2">Members</th></tr>
<!-- THIS IS NOT NECESSARY UNLESS YOU WANT TO ADD FORMS WITH JAVASCRIPT-->
<div id="id_empty_form" style="display:none;">
{{ memberformset.empty_form }}
</div>
<!-- END NOT NECESSARY-->
{% for form in memberformset.forms %}
{{ form }}
{% endfor %}
{% endwith %}
</tbody>
</table>
<input type="submit" value="Save" />
</form>
I'm trying to do a form, with gender choices. The user could choice between male or female.
What I have now in forms.py:
class GenderForm(forms.Form):
demo = DemoData.objects.all()
GENDER_CHOICES = [
('Male', 'Masculino'),
('Female', 'Feminino')]
gender = forms.ModelChoiceField(demo, widget=Select(), required=True)
choices_distlabel = [('', '')] + GENDER_CHOICES
gender.choices = choices_distlabel
in the template:
<form action="" method="post">
{% for field in form_gender %}
{{ field }}
{% endfor %}
<input type="submit" value="Submit" />
</form>
{% if idgender %}
<img src="/age_gender/{{ idgender }}.png" alt="Graph"/>
{% endif %}
the views:
if form_gender.is_valid():
gender = form_gender.cleaned_data['gender']
gender = gender.gender
if gender:
idgender = gender
return render_to_response('age.html', {'form_gender': form_gender, 'idgender': idgender })
the form is done and works, but the problem is when I click on the submit button nothing happen. He is not given me the information
You have to define url where post data will be sent
This will send post data to url /my_app/my_view/
<form action="/my_app/my_view/" method="post">
{% for field in form_gender %}
{{ field }}
{% endfor %}
<input type="submit" value="Submit" />
</form>
This will send post data to current url you are on.
<form action="." method="post">
{% for field in form_gender %}
{{ field }}
{% endfor %}
<input type="submit" value="Submit" />
</form>
I don't understand why you've defined DemoDataForm in both models.py and forms.py, once as a ModelForm and once as a plain form. Because of that, it's impossible to tell from the code you've posted exactly which class you're instantiating.
I would say, drop the version in forms.py, move the one in models.py into forms.py, and use that. But first you'll need to fix a slight bug - instead of:
fields = ('gender')
you need
fields = ('gender',)
because a one-item tuple always needs a comma, otherwise Python will try to iterate through the string.
