Please suggest to define if condition in DOJO DTL
Ex:
{% if item.Status == "Pending" %}
Your coding
{% else %}
This is not working
Try
{% ifequal item.status "Pending" %}

Is something like this possible in a template?
{% if request.path == url 'posts:post_detail' pk=instance.id %}
If not, how can I achieve this result being True? I want to this to be true when user is looking at a specific post such as post/1.
Yes, you can using the as var syntax:
{% url 'posts:post_detail' pk=instance.id as the_url %}
...
{% if request.path == the_url %}
...do something
{% endif %}
I want to write a template that renders something only one time.
My idea is to create a flag variable to check it is the first time.
My code
{% with "true" as data %}
{% if data == "true" %}
//do something
** set data to "false" **
{% else %}
//do something
{% endif %}
{% endwith %}
I don't know How to change a variable in django template. Is it possible? Or is there a better way to do this?
This can be done with a Django custom filter
django custom filter
def update_variable(value):
data = value
return data
register.filter('update_variable', update_variable)
{% with "true" as data %}
{% if data == "true" %}
//do somethings
{{update_variable|value_that_you_want}}
{% else %}
//do somethings
{% endif %}
{% endwith %}
NIKHIL RANE's answer doesn't work for me. Custom simple_tag() can be used to do the job:
#register.simple_tag
def update_variable(value):
"""Allows to update existing variable in template"""
return value
and then use it like this:
{% with True as flag %}
{% if flag %}
//do somethings
{% update_variable False as flag %}
{% else %}
//do somethings
{% endif %}
{% endwith %}
My coding is:
views
def showThread(request, thread_id)
post_list = Post.objects.filter(id = thread_id)
post_likes = PostLikes.objects.all()
return render_to_response('show.html',locals(),context_instance=RequestContext(request))
models:
class Post(models.Model):
subject = models.CharField(max_length = 250)
body = models.TextField()
thread = models.ForeignKey('self', null = True, editable = False )
Show.html:
{% for post in post_list %}
{{post.id}}{{post.subject}}
{% endfor %}
{% for post_like in post_likes %}
{% if post_like.post_id == post.id and post_like.user_id == user.id %}
U like this post{{post}}
{% else %}
{{post}}
{% endif %}
{% endfor %}
In the show.html, else part, it displays the values again and again. But i need only one time.How can i break the for loop when i enter into else condition.Please help me..
Django's for tag doesn't provide you with any means to break out of the loop. You'll simply have to filter the collection in your own view and slice it after the point your condition fails and supply that to your template.
You can use the django custom template tag found in this django snippets page. If you have doubts on using it, go to this page to learn about custom template tags.
Then load the template tag in your template using {% load loop_break %}. Then you can break the for loop as given below:
{% for post_like in post_likes %}
{% if post_like.post_id == post.id and post_like.user_id == user.id %}
U like this post{{post}}
{% else %}
{{post}}
{{ forloop|break }}
{% endif %}
{% endfor %}
Here the for loop will break when it enters the else part.
you could probably use ifchanged tag:
https://docs.djangoproject.com/en/dev/ref/templates/builtins/?from=olddocs#ifchanged
However, you probably should consider moving this logic to view.
If you can structure your if statement to detect when you want to output nothing, you can simply put nothing inside your else clause:
{% for post_like in post_likes %}
{% if post_like.post_id == post.id and post_like.user_id == user.id %}
U like this post{{post}}
{% else %}
{% if forloop.first %}
{{post}}
{%else%}{%endif%}
{% endif %}
{% endfor %}
The above might not do quite what you want - you will have to tweak it yourself. The only thing you can't do is set a flag that this is the first entry into the else clause.
I am trying to run two tests:
{% if profile.id != 100 or profile.location == NULL %}
however it seems to not work. I couldn't find in the docs why this isn't working. Any ideas?
EDIT:
In the SQL db, the value for profile.location is NULL. The rendered result is None.
EDIT 2:
Here is the full chain. There are 4 ways to grab a user's location. It is a giant mess as you can see...
{% if profile.city.id != 104 or profile.city %}
{{profile.city}}
{% else %}
{% if profile.mylocation != '' %}
{{ profile.mylocation }}
{% else %}
{% if profile.fbconnect == 1 and profile.location != '' and profile.location != "None" %}
{{profile.location}}
{% else %}
{% if profile.sglocation.city %}{{profile.sglocation.city}}{% else %}{{profile.sglocation.country}}{% endif %}
{% endif %}
{% endif %}
{% endif %}
There's no NULL. Try:
{% if profile.id != 100 or not profile.location %}
If I were you, I would throw all that logic back into Python, for example:
class Profile(models.Model):
[your model fields and stuff]
def get_location(self):
[your location logic]
Then in the template you can just do:
{{ profile.get_location }}
How can I know if a checkbox is checked (True, 1) having just the {{ form.checkbox }} form-tag?
'activo' is defined as (True, 1) in the db.
My template is:
{{ form.activo }}
RESULTS:
<input id="id_activo" type="checkbox" name="activo" checked="checked"/>
{{ form.activo.data }}
RESULTS:
False
{{ form.activo.value }}
RESULTS:
""
Yet no 1's or True's are coming through. :S
Any hint is appreciated. =')
It is checked if request.POST.has_key('activo') or the {{ form.activo.data }} actually returns True when initialized with request.POST.
Your question isn't quite clear, but maybe your problem has something to do with the fact, that browsers don't put anything in the POST data for an unchecked checkbox.
This made things complicated for me when I had to differentiate between a checkbox not being displayed at all and a displayed checkbox not having been checked. Just from looking at the POST data you can't tell those two cases apart.
Following on from your reply to mbarkhau's answer, using instance= doesn't make the form bound, it just provides default values to the form.
Here's the logic in a template:
{% if form.is_bound %}
{% if form.initial.activo %}
Checked.
{% else %}
Not checked.
{% endif %}
{% else %}
{% if form.activo.data %}
Checked.
{% else %}
Not checked
{% endif %}
{% endif %}
But it makes more sense to do this logic in the view and pass extra context. Something like:
context_data = {...}
if form.is_bound:
activo = form.data.get('activo')
else:
activo = form.initial.get('activo')
context_data['activo'] = bool(activo)
return render_to_response('your_template.html', context_data)
If you want a boolean condition in templates this should work:
{% if form.activo %}
--
{% else %}
---
{% endif %}
