I am using Django 1.10 and trying to find a way to check the error code of a form inside of the template. So I tried a few things, like errors.as_data or errors.as_json, but I was unable to parse the different values (except by using javascript). Could it be something like this ?
<p>{% for key, value in form.errors.items %}
{{ value }}
{% if code == 'inactive_account'%}
// do some stuff
{% endif %}
{% endfor %}
</p>
But I don't know how to get this error code. Any suggestion ?
PS : I know that a solution would be to do it inside of the view, but since I am using a django already-made one, I would prefer not to do it.
The dictionary form.errors does not contain the ValidationError instances. You need to use the as_data method.
Note that you need to loop through the list of errors for each key, and then you can check the code.
{% for key, key_errors in form.errors.as_data.items %}
{{ key }}
{% for error in key_errors %}
{% if error.code == 'inactive_account'%}
// do some stuff
{% endif %}
{% endfor %}
{% endfor %}
