when I define something like this:

Here's what appears in the documentation. Few hints:

I think you should include pagar_pase in your list_display tuple and also you are better off using format_html than the triple quotes.

from django.utils.html import format_html

class Person(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    color_code = models.CharField(max_length=6)

    def colored_name(self):
        return format_html('<span style="color: #{0};">{1} {2}</span>',
                           self.color_code,
                           self.first_name,
                           self.last_name)

    colored_name.allow_tags = True

class PersonAdmin(admin.ModelAdmin):
    list_display = ('first_name', 'last_name', 'colored_name')

Here, they define first the model and then create a ModelAdmin and there, they include the method's name in the list_display which you're missing.

Your code should be like this:

class MyModelAdmin(admin.ModelAdmin):
    list_display = ('foo', 'my_custom_display', 'pagar_pase')

    def pagar_pase(self, obj):
        # I like more format_html here.
        return """<form action="." method="post">Action</form> """
    pagar_pase.description = 'Testing form output'
    pagar_pase.allow_tags = True

Hope it helps!

Ok, so the problem here is that list_display is inside an html form, so I was trying to display a form inside a form, that is a bad idea... and below explains why

Can you nest html forms?

Hope it helps.

It looks like you are trying to trigger an action on an item listed. Perhaps this is better executed by writing your own admin actions.

Here is an example:

def pagar_pase(modeladmin, request, queryset):
    """ Does something with each objects selected """
    selected_objects = queryset.all()
    for i in selected_objects:
        # do something with i

pagar_pase.short_description = 'Testing form output'

class MyModelAdmin(admin.ModelAdmin):
    list_display = ('foo', 'my_custom_display')
    actions = [pagar_pase]
