I am trying to implement a simple UpdateView, but I want to use my own template. Using djangos auto_population is working, but not what I want, because I have lots of fields formatted differently.
<form method="post" action="#">
{% csrf_token %}
{{ form.as_p }}
<input type="submit">
</form>
But I want to use my own form template which looks like this:
edit_template.html
<form class="form-horizontal" role="form" method="POST" action="{% url 'update' pk=abc %}">
{% csrf_token %}
<input name='varX' id="varX" type="text" placeholder="" class="form-class">
<input name='varY' id="varY" type="text" placeholder="" class="form-class">
</form>
views.py
class ModelUpdate(UpdateView):
model = MyModel
fields = ['varX','varY']
Now I would like that form to be populated with my object data, but the form is empty.
UpdateView is also passing the data twice to the template: One as 'object' and one as 'mymodel'.
I also tried updating
get_context_data
by adding
context.update( model_to_dict(myModelData))
But that also does not change anything.
How can I populate my custom form using djangos class-based views?
Try this:
def get_initial(self):
initial = super().get_initial()
initial['my_form_field1'] = self.request.something
return initial
Have a look at django-widget-tweaks, you first need to check for any non field errors and then loopt through the fields one by one.

I have this code snippet in template.
<form method="POST" novalidate>
{% csrf_token %}
{{ form }}
{{ form2.as_p }}
<button type="submit" class="btn btn-secondary">Search</button>
</form>
And in forms.py there are two forms (not ModelForm, but only Form).
form searches data in first db and form2 search data in second db and displays the results. The second form has only one field and I'd like to have something like this in
a view.
if request.method == "POST":
if form.is_valid():
# extract data from the first db
if form2.is_valid()
# extract a few more data from the second db
The field in the second form is not required for the user to fill in. If the user fills it in the user gets only more data displayed.
I solved it partially with the novalidate in HTML. But what I'd like to have is the validation of the first form and the second form with its one form field can be empty.
Is there some django feature to achieve this result?
something like this?
<form method="POST">
{% csrf_token %}
{{ form.novalidate }}
{{ form2.as_p }}
<button type="submit" class="btn btn-secondary">Search</button>
</form>
How do I update a single field in django using html template?
I have an html page to add records. I need to make an html page only to update a single field of the model. How do I do that. And what should be the view function for it.
It's really quite simple with an UpdateView.
It takes care of building a generic ModelForm class for the model too.
class UpdateSomeFieldView(views.UpdateView):
fields = ('some_field',)
model = MyModel
For the template, all you really need there is a
<form method="post">
{% csrf_token %}
{{ form.errors }}
<table>{{ form.as_table }}</table>
<input type="submit" />
</form>
I need to create function based or class based view which can edit/update multiple forms in one page. How to create this?
You should be able to have more than one form appear on a template by passing two different form variables in the view. Something like this:
def formview(request):
if request.method == 'POST'
form1 = form.Form1()
form2 = form.Form2()
context = {'form1': form1, 'form2': form2}
Then in your template you simply need to handle each form within the form tags like so:
<form action="" method="post">
{% csrf_token %}
{{ form1.as_p }}
{{ form2.as_p }}
<input class="btn btn-primary" type="submit" value="Submit">
</form>
I am using django-webtest to create automated functional tests for my application.
As I have multiple forms on a single web page, I'm currently using a hard-coded index to select the form of interest. For instance:
# Forms on this page are: forms[0] = Establishment form,
# forms[1]= School Form
school_form = school_page.forms[1]
school_form['phone'] = self.school_phone_number
school_form.submit(value='Submit')
I would like to use the form id instead of a hard-coded index to select the form of interest, so that the code is maintainable. But when I print school_form.id in my code, the value is None.
Template is:
<form action="" method="post" >
{% csrf_token %}
<p>
{{ establishment_form|crispy }}
<br><br>
{{ school_form|crispy }}
</p>
<button type="submit" class="btn btn-lg btn-primary">Submit</button>
I couldn't locate in the Django documentation how to assign the form id (not the form field id) to a ModelForm. Could someone help me with this?
I'm using Django 1.7, django-webtest 1.7.8, WebTest 2.0.18 and django-crispy-forms 1.4.0.
Django forms aren't responsible for outputting the form element itself. So there is nothing to be done at the form declaration level.
You can always pass an attribute from the view and use it in your template:
<form id="{{ form_id_from_view }}" action="." method="POST">
You can directly assign the id to the form element in your template.
<form id="my_id" name="some_name" action="/my/url/" method="POST">
I have a formset which i initialize it in view. one of the form's fields is FileField. and I have to show user the name of his/her previous file name. Because i can't initialize FileField, i want to send file names in list. (I mean for example when you have a Charfield, you can initialize it in views and when you render to template, you will see an input filled with that data, but when you have file upload field you can't filled it in views and sends to template). i don't know how i can loop over forms in formset and list at the same time. And the other thing is when i initialize forms in formset and render to template (I mean for example write data['form-0-Team']='team1' but i can't write data['form-0-Team']='a.png' , so when i render to template, i see field named 'Team' is filled (value=team1) and field named 'File' is not filled and the error 'thid field is required' id shown. ) although it's the first time i'm visiting this page and my method isn't POST. (USUALLY form errors are shown when user clicks on submit and in views it checks if request.method == 'POST', then checks if form.is_valid, it return to template and shows errors, but in mine, it shows errors at the first time euser is visiting the page and before he/she posts data).
I wish i could say my problem. can you please guide me solve this? really thanks.
def myFunc(request):
flagFormSet = formset_factory(FlagFileBaseForm)
if request.method == 'POST':
formset = flagFormSet(request.POST, request.FILES)
if formset.is_valid():
# do s.th
else:
data = {
'form-TOTAL_FORMS': 5,
'form-INITIAL_FORMS': u'0',
'form-MAX_NUM_FORMS': u'',
# add initial form data to it
}
list=['a.png', 'b.png', 'c.png', 'd.png' , 'f.png']
formset = flagFormSet(data)
return render_to_response('myPage.html', RequestContext(request, { 'formset': formset, 'list':list}))
and my template:
<form method="post" action="" enctype="multipart/form-data">
{{ formset.management_form }}
{% for form in formset.forms %}
<div class="form">
<div class="form-row Team">
<div>
<label class="required" for="id_Team">Team:</label>
{{ form.Team }}
{{ form.Team.errors }}
</div>
</div>
<div class="form-row File">
<div>
<label class="required" for="id_File">File:</label>
{{ form.File }}
{{ form.File.errors }}
</div>
#here i want show the name of previous file
</div>
</div>
{% endfor %}
</form>
EDIT:
current result (while request is not post, it shows error)
desired result (form without error with file names)
In Django Templates, if you are trying to render a form that has a FileField. You must pass replace
<form method="post" action="">
with
<form method="POST" enctype="multipart/form-data">
https://docs.djangoproject.com/en/dev/ref/forms/api/#binding-uploaded-files-to-a-form
I'm afraid I don't really understand your question, so apologies if this doesn't help..
If your list is arbitary (as it looks from your question), then you could use django's built in forloop counter to construct your file names -
{% for form in formset %}
{{ form }}
<input type="text" name="file_name" value="{% forloop.counter %}.png">
{% endfor %}
Alternatively have a look at python's zip function. You could use it to build an object that includes both the names and the forms and pass that to your template.
