UPDATE 1: Code that gets me done with 1) (don't forget tot pass CHOICES to the BooleanField in the model)
<pre class="lang-py prettyprint-override"><code>from main.models import TagCat

class MyTagCatAdminForm(forms.ModelForm):
 class Meta:
 model = TagCat
 widgets = {

 fields = '__all__' # required for Django 3.x
 
class TagCatAdmin(admin.ModelAdmin):
 form = MyTagCatAdminForm


admin.site.register(TagCat, TagCatAdmin)
</code></pre>
The radio buttons appear ugly and displaced, but at least, they work
<ol start="2">
<li>I solved with following info in MyModel.py:</li>
</ol>
<pre class="lang-py prettyprint-override"><code>BYADMIN_CHOICES = (
 (1, &quot;Yes&quot;),

blocks|key|3006965|text|有另一种方法可以做到这一点，那就是，如果您希望相同类型的每个字段都具有相同的小部件，则IMO要容易得多。这是通过指定ModelAdmin的formfield_overrides来完成的。例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3006966|class+MyModelAdmin(admin.ModelAdmin):
++++formfield_overrides+=+{
++++++++models.TextField:+{'widget':+RichTextEditorWidget},

There is another way to do this that is, IMO much easier if you want every field of the same type to have the same widget. This is done by specifying a formfield_overrides to the ModelAdmin. For example:

<pre><code>class MyModelAdmin(admin.ModelAdmin):
 formfield_overrides = {
 models.TextField: {'widget': RichTextEditorWidget},
 }
</code></pre>

blocks|key|292275|text|下面是mgPePe响应的一个更动态的扩展：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|292276|class+MyAdminForm(forms.ModelForm):

++++++++super(MyAdminForm,+self).__init__(*args,+**kwargs)

class+MyAdmin(admin.ModelAdmin):
++++fields+=+['name',+'by_admin']
++++form+=+MyAdminForm|code-block|syntax|javascript|292277|这样你就可以完全控制这些领域了。|292278|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Here is a more dynamic extension of mgPePe's response:

<pre><code>class MyAdminForm(forms.ModelForm):
 def __init__(self, *args, **kwargs):
 super(MyAdminForm, self).__init__(*args, **kwargs)

 self.fields['by_admin'].label = 'My new label'
 self.fields['by_admin'].widget = forms.RadioSelect()


 class Meta:
 model = TagCat

class MyAdmin(admin.ModelAdmin):
 fields = ['name', 'by_admin']
 form = MyAdminForm
</code></pre>

This way you get full control over the fields.

I have a model with a boolean value like that:

<pre><code>class TagCat(models.Model):
 by_admin = models.BooleanField(default=True) 
</code></pre>

This appears as a checkbox in admin. 

<ol>
<li>How could I use this as a radio button in admin? </li>
<li>Also, how do I make it be always with a certain selected value in admin? </li>
<li>Also, I want the default value to be the opposite, when a non-admin user adds a <code>TagCat</code>. This field should be hidden from him.</li>
</ol>

Can someone tell me how to do this? Django documentation doesn't seem to go in such details.
