[PYTHON] [Django] Install radio buttons and shape markup

environment

Django 1.10.5

Make form.py

First, form.py, which is the source of form There is also a way to use ModelForm, but this time we will create something that is completed in form.py

`form.py`


from django import forms
from django.contrib.admin import widgets
import os

CHOICE = {
    ('0','cute'),
    ('1','cool'),
    ('2','passion'),
}

form SampleForm(forms.Form):
	select = forms.ChoiceField(label='attribute', widget=forms.RadioSelect, choices= CHOICE, initial=0)

You can specify the items selected by default by setting ʻinitial = index Ifrequired = False` does not require selection, it is better to remove it.

Make views.py

This time I will simply write a view that passes only this form

`views.py`


from django.shortcuts import render, get_object_or_404, redirect
from forms.forms import *

def sample_view(request):
	form = SampleForm
	return render(request,
		project/sample.html,
		{"form" : form}
	)

Call form on html side

As it is Let's do it

`sample.html`


{{ form }}

Basically, this is all you need, but if there are multiple input items in one form, you can control them individually as follows.

`sample.html`


{{ form.select.label　}}{{ form.select}}

You can easily install a radio button above, but the drawback is that the generated markup is surrounded by `

attribute
<ul id="id_select">
	<li>
		<label for="id_select_0">
			<input checked="checked" id="id_select_0" name="purpose" type="radio" value="0" />
cute
		</label>
	</li>
	<li>
		....
</ul>

Fine control over the generated markup

As you can see in the Official Reference, you have more control over the markup generated by turning with for. can For example, if you do as follows

`sample.html`


{{ form.select.label }}
{% for radio in form.select %}
	{{ radio.tag }}
	<label>{{ radio.choice_label }}</label>
{% endfor %}

Produces something that is (and will be) manageable

attribute
<input checked="checked" id="id_select_0" name="select" type="radio" value="0" />
<label>cute</label>
<input id="id_select_1" name="select" type="radio" value="1" />
<label>cool</label>         
...

`sample.html`


{{ form.select.label }}
{% for radio in form.select %}
	{{ radio.tag }}
	<label for="id_select_{{ radio.index }}">{{ radio.choice_label }}</label>
{% endfor %}

If you do this

attribute
<input checked="checked" id="id_select_0" name="select" type="radio" value="0" />
<label for="id_select_0">cute</label>
<input id="id_select_1" name="select" type="radio" value="1" />
<label for="id_select_1">cool</label>         
...

Yes
