I am using Django 2.0.4 with bootstrapform https://github.com/tzangms/django-bootstrap-form . I would like to render my field and label separately in my template.
Currently I can render the field using:
{% load bootstrap %}
{{ form.fieldname|bootstrap }}
I would to find a way to separate the render of the label from the field so that I can insert text next to the label for selecting tool-tip. Is anyone able to point me in the right direction to achieve this? Any help will be much appreciated!
Try the following : This link provides more info
{{ form.field_name }} will render the field
{{ form.field_name.label }} will render the label
{{ form.field_name.id_for_label }} the ID

In my flask app, I have 2 instances of CKEditor on 2 different files.
<div>
{{ ckeditor.create(name="message_body") }}
{{ ckeditor.load(pkg_type="standard") }}
{{ ckeditor.config(name="message_body", width=1000, height=500) }}
</div>
and
<div>
{{ ckeditor.create(name="newsletter_body") }}
{{ ckeditor.load(pkg_type="standard") }}
{{ ckeditor.config(name="newsletter_body", width=1000, height=500) }}
</div>
Each of those <div> are in a {% block main %}
I'm getting the data from from 2 different file with these lines:
request.form.get("message_body")
and
request.form.get("newsletter_body")
All seems fine, I get the data but in my browser I get this errors:
[CKEDITOR] Error code: editor-element-conflict.
Object { editorName: "message_body" }
The related docs read this:
Description: There is already an editor’s instance attached to the provided element and attaching another one to it is not allowed.
Additional data:
editorName: The name of the already attached editor.
But I don't understand why. Can any one help me get rid of these errors?
Many thanks
I just release 0.4.5 to fix this, please upgrade:
pip install -U flask-ckeditor
The reason behind this error is:
When you add a "ckeditor" class to a textarea element, CKEditor will try to initialize a CKEditor editor box on top of it. At the same time, if you initialize a CKEditor editor box manually with CKEDITOR.replace(...) (which is what the ckeditor.config() does), the error happens: you can't initialize two CKEditor editor box on one textarea element.
I have two for loops from which the first one (for i in var) is for getting the posts and the other is for getting the tags (ManyToManyField in the Post model) for that post:
{% for i in var %}
{% for j in i.tags.all %}
{{ j.name }}
{% endfor %}
{% endfor %}
Why won't this work?
EDIT:
Here is what the variables contain:
var:
[<SearchResult: myapp.post (pk='1')>, <SearchResult: myapp.post (pk='2')>]
and here is {{ i.tags }}:
<django.db.models.fields.related.ManyRelatedManager object at 0x1620dd0>
If I try to iterate it with .all it returns nothing.
EDIT 2:
This might be the problem - var is a variable from a SearchQuerySet (django haystack):
var = SearchQuerySet().all()
Inside the template, the j is something like <SearchResult: myapp.post (pk='1')>, which does not have .tags attributes. Try for j in i.object.tags.all, the .object refers the actual Model instance.
Note that Django normally does not complain about trying of accessing non-existing attributes (i.tags here) during template rendering. Hence rendering nothing may also mean incorrect attributes referring.
Solved it by adding the tag field into the haystack searchindex. Now it outputs the list of tags. Thank you all for your help!
Is there any way to get the id of a field in a template?
In the HTML I get: <input name="field_name" id="id_field_name"...
I know I can get the name with {{ field.html_name }}, but is there anything similar for getting the id?
Or can I only get it like this: id_{{ field.html_name }}?
You can get the ID like this:
{{ field.auto_id }}
You can also use id_for_label:
{{ field.id_for_label }}
This doesn't work for every form field.
For instance {{ form.address.auto_id }} works while {{ form.address.auto_name }} will not.
However you can use {{ form.address.html_name }} to get the equivalent answer.
Here are the docs
From the documentation-
each form field has an ID attribute set to id_<field-name>
, which is referenced by the accompanying label tag. This is important in ensuring that forms are accessible to assistive technology such as screen reader software. You can also customize the way in which labels and ids are generated.
So I would like to say id_field-name , you collect the field name from the model.
Here is the link to the documentation
In Django 2 you can retrieve the ID for a specific field using {{ field.id_for_label }}
This is documented here.
I have a custom template tag:
def uploads_for_user(user):
uploads = Uploads.objects.filter(uploaded_by=user, problem_upload=False)
num_uploads = uploads.count()
return num_uploads
and I'd like to do something like this, so I can pluralize properly:
{% with uploads_for_user leader as upload_count %}
{{ upload_count }} upload{{ upload_count|pluralize }}
{% endwith %}
However, uploads_for_user leader doesn't work in this context, because the 'with' tag expects a single value - Django returns:
TemplateSyntaxError at /upload/
u'with' expected format is 'value as name'
Any idea how I can get round this?
You could turn it into a filter:
{% with user|uploads_for as upload_count %}
While a filter would still work, the current answer to this question would be to use assignment tags, introduced in Django 1.4.
So the solution would be very similar to your original attempt:
{% uploads_for_user leader as upload_count %}
{{ upload_count }} upload{{ upload_count|pluralize }}
Update: As per the docs assignment tags are deprecated since Django 1.9 (simple_tag can now store results in a template variable and should be used instead)
In Django 1.9 django.template.Library.assignment_tag() is depricated:
simple_tag can now store results in a template variable and should be used instead.
So, now simple tag we can use like a:
It’s possible to store the tag results in a template variable rather
than directly outputting it. This is done by using the as argument
followed by the variable name. Doing so enables you to output the
content yourself where you see fit:
{% get_current_time "%Y-%m-%d %I:%M %p" as the_time %}
<p>The time is {{ the_time }}.</p>
I am trying to install django-photologue. Everything seems ok, because I install and set up following the official guidelines. I have to upload some photos as examples. However, when viewing a photo or gallery details , then an error as follows:
Caught an exception while rendering: 'Photo' object has no attribute 'get_thumbnail_url'
I tried to remove the following code from the file photo_detail.html
{% if object.public_galleries %}
<h2>This photo is found in the following galleries:</h2>
<ol>
{% for gallery in object.public_galleries %}
<li>{%previous_in_gallery object gallery%} {{ gallery.title }} {%next_in_gallery object gallery%}</li>
{% endfor %}
</ol>
{% endif %}
No more errors, but pictures do not show up. If you click on the link will still lead to correct photographs to see. I think the problem in:
{{ object.get_display_url }}
It is totally not return any value.
Please help me solve this problem. Thanks!
Did you run python manage.py plinit after install and opt to create both a thumbnail and display photosize? These photosizes need to be defined in your database.
In other versions, you have to edit photologue/templates/photolog/tags/next_in_gallery.html and replace
{{ photo.get_thumbnail_url }}
with
{{ photo.thumbnail.url }}
Same for photologue/templates/photolog/tags/prev_in_gallery.html.
Honestly from looking at the source, it looks like a bug in the project. If you search the source, thumbnail doesn't seem to be a field within the Photo class (get_FIELD_url is an easy way to access an ImageField's url btw.) So I would recommend tinkering with the source or finding another project. I might be wrong though but that's what my ~5 minute scan of the project found.
