Crispy forms and its "coercing to unicode need string or buffer nonetype found"

[RompePC]

I was working on an admin panel, and when I try to get to the add/update view of the model, it just throws this error. I've been checking Google for all the morning, but the solutions I've just found aren't the problem I've (no problem with unicode, I check if the related object is None, etc.).

The exception throwed is (line 28):

coercing to Unicode: need string or buffer, NoneType found

18
19 {% if field|is_checkboxselectmultiple %}
20 {% include 'bootstrap3/layout/checkboxselectmultiple.html' %}
21 {% endif %}
22
23 {% if field|is_radioselect %}
24 {% include 'bootstrap3/layout/radioselect.html' %}
25 {% endif %}
26
27 {% if not field|is_checkboxselectmultiple and not field|is_radioselect %}
28 {% if field|is_checkbox and form_show_labels %}
29 <label for="{{ field.id_for_label }}" class="{% if field.field.required %} requiredField{% endif %}">
30 {% crispy_field field %}
31 {{ field.label|safe }}
32 {% include 'bootstrap3/layout/help_text_and_errors.html' %}
33 </label>
34 {% else %}
35 <div class="controls {{ field_class }}">
36 {% crispy_field field %}
37 {% include 'bootstrap3/layout/help_text_and_errors.html' %}
38 </div>

Hi there,

I apprecciate the help, but the models' code is secret (I'm not allowed to show it anywhere).

It is like it sends a non-existent field to the form, and don't know why. And the model is the same as the previous version, its very weird. And didn't found anything about that error in a crispy-form.

I'm sorry for the problems.

Ok, I just did again a unicode(..) call to a method that before worked without it. Sincerely, I just have no idea why now I need to do it.

Solved.
