I was wondering how you can assign a value to a django form field in the template.
I know that there is other ways to assign an initial value in django, but I need to assign the value in the template because the variable is only present in the template.
The way to do this with a normal html form would be this:
{% for thing in things %}
<p> {{ thing.content }} </p>
<!-- Reply form -->
<form>
<input type="hidden" name="replyingto" value="{{ thing.number }}">
<input type="text" label="Reply"></input>
</form>
{% endfor %}
However, I need to use a django form.
I also know there is a way to assign a label to a field in the template, like this:
{{ form.non_field_errors }}
{{ form.field.errors }}
<label for="{{ form.field.id_for_label }}"> field </label>
{{ form.field }}
So my question is basically how you would go about doing the example above but instead of assigning a label, assign a value.
I've found a solution!
What I did was type the html manually as Daniel suggested and assigned the value that way.
For anyone who is wondering how I did it here is an example.
The is_valid() method is used to perform validation for each field of the form, it is defined in Django Form class. It returns True if data is valid and place all data into a cleaned_data attribute.
you do it in Python, which can then be available to the HTML form or generator
in forms.py
you can set the initial
property to define the default value of the field.
ex: name = forms.CharField(initial='class')
or dynamically in views.py
you can use a dict
.
ex: f = CommentForm(initial={'name': 'instance'})
Once available within the form
instance you can use {{ form.field.value }}
in your HTML or automatically with a generator
