I am sending a formset to my template. I want to add some style to it, so I need to access his variables.
I took the following code from documentation, where they print the form and it has some attributes, amongside them the name="form-0-title".
for form in formset:
print(form.as_table())
<tr><th><label for="id_form-0-title">Title:</label></th><td><input type="text" name="form-0-title" value="Django is now open source" id="id_form-0-title"></td></tr>
...
As I want to style my forms, I need to give the inputs a name to know how to treat them in the backend. When I do the following in the templates
{{ proficiency_form.management_form }}
{% for form in proficiency_form %}
{{form.title.name}}
{% endfor %}
I get title, title, ... instead of id_form-0-title, id_form-1-title, ...
How can I get the correct name in the templates?
You can easily get the input's name of your fields like so:
{{ proficiency_form.management_form }}
{% for form in proficiency_form %}
{{form.title.html_name}}
{% endfor %}
If you want to get the label's id, you can consider this approach:
{{ proficiency_form.management_form }}
{% for form in proficiency_form %}
{{form.title.id_for_label}}
{% endfor %}
Read more about it in the official Docs.

Doing this works
{% for comment in comments %}
{{ comment.user }}
{% endfor %}
However, I want to get all the comment.user values in the dictionary without using a for loop. Is this possible?
I ask because I need to do this check
{% if name in comment.user %} # check if name is in any one of the comments
# do something
{% endif %}
Basically, you need to get all the distinct users from comments. You have to do it in the view and pass users queryset back into the template:
users = User.objects.filter(comment__in=comments).distinct()
I'd need to pass some data from my manually generated form to the template, and would need to check the presence of that information there.
I'm generating my form as such (in the __init__ part):
for i in days_in_month:
self.fields["info_%s" % i] = forms.ChoiceField(label="%s" % i.strftime("%a %d-%m-%Y"),
required=False,
choices=Information._meta.get_field('info').choices,
widget=forms.Select(attrs={'something': 'test'}))
What I would like to do, is to check in the template whether the attribute something is set, and if so, display its value (in the example above: test).
Any idea?
I tried with {{ field.attribute }} as per Access form field attributes in templated Django and the below:
{% for field in form %}
{{ field.label_tag }} {{ field }}
{{ field.widget.attrs.something }}
{% endfor %}
... but that doesn't work (invalid).
Ultimately I want to do something similar to:
{% if field.widget.attrs.something %}{{ field.widget.attrs.something }}{% endif %}
That would be
{{ field.field.widget.attrs.something }}
{% for field in columnMetaData %}
{{field}}
{% endfor %}
Code above only displays <input>...</input>
But how to get and <label></label>, because labels exists in columnMetaData
I forgot to say that columnMetaData is ModelForm
NEW UPDATE
Just another question. Is there way to add class in each {{field}} ?
And field to be like this: <input type="" class="something" ></input>
You could use attrs to set classes for your field. Usage: field=forms.CharField(attrs={'class': 'some-class'})
Like that :
{% for field in columnMetaData %}
{{ field.name.label }}
{% endfor %}
I like the convenient output form method {{ form.as_ul }} but is there a way I can still continue to use it but capture all the errors upfront instead of displaying the error just above each field.
I understand that there are ways to loop through each form element and so on as mentioned in django docs but I want to continue to utilize the capability of form.as_ul() except get control over error display.
Solved this problem by using Reusable Form Templates.
Its simple...
Create a reusable template with the following code snippets based on your need.
If you want to display all errors right at the top of the form...
{% if form %}
{% if form.errors %}
{% for field in form %}
{{field.errors}}
{% endfor %}
{% endif %}
{% for field in form %}
<li>{{ field.label_tag }}: {{ field }}</li>
{% endfor %}
{% endif %}
If you want to display all errors right after each form field without the default html elements around error use...
{% for field in form %}
{{ field.label_tag }}: {{ field }}
{% for error in field.errors %}{{ error }}{% endfor %}
{% endfor %}
Used the second template and created a Inclusion Tag
The only way I see is to inherit the new form class from forms.Form and alter as_ul method as you like. Which isn't very good if you are going to use third-party forms like login form and so on (they won't have this method).
I think the best solution is to create your own inclusion tag and render form with it. It will be as short as as_ul ({% render_form form %}) but very flexible, it will work with all forms and won't mix HTML and Python code.
I still think the customization for rendering form in templates is quite flexible. I usually do this for my webapps. You may work with a bit javascript and css but not a big problem. Moreover, I think we should try to make the app simple.
I want to customize the layout of forms in a formset (that is, I don't want to use .as_table() or .as_p() and the like). I'm trying to get the name of a form field for use in its label's for attribute, but I'm not sure how to go about it. I'm hoping that I won't need to construct a new name/ID for the field from scratch. Here's an example of what I'm working with right now:
{% for form in formset.forms %}
<!-- The field for the "path" form field -->
<label for="{{what do I put here?}}">{{form.fields.path.label}}:</label><input type="text" id="{{django creates this one; do I have to do my own with the for loop counter or something?}}" name="{{probably the same as id}}" />
{% endfor %}
Is there any sort of "create ID for formset field" sort of method?
This is likely what you want.
for="{{ form.your_field.html_name }}"
First, you want to use the form element's id, instead of name.
I tried Django 1.3 Alpha-1 and the following worked:
{% for form in formset.forms %}
<label for="{{ form.my_field.auto_id }}">{{ form.my_field.label }}</label>
{{ form.my_field }}
{% endfor %}
Enjoy!
