Re: image not showing on page

[Andréas Kühne]

Why do you have  a ; in the src part of the img tag? I am guessing that you
get a 404 now?

Andréas

Learn to use your browsers debugging tools and read the output from the 
Django server logs. That will make it much easier for you to find the 
cause of your problems.

I'm sorry, I don't understand what that's supposed to mean?

I would assume that the log from Django or your web browsers console

What is the output from both logs?

Django + hosted videos and user rights

[Moreplavec]

Greetings,

i'd like to have online courses in my website. I found it quite difficult 
to serve and protect videos (i'm not so skilled in Django), so i'd like to 
try to use some service like Vimeo to make my life easier and solve 
serving/playing and video protection.

Right now i have website based on Django 2.x with Wagtail CMS to easy 
manage website content. I'd like to add pages with type Online course, 
which will be accessible only to users with purchase (access will be 
granted after Orders table check and only to bought courses). Videos will 
be inserted in Online course page. The only problem is, how to "hide" or 
modify video urls to prevent from download/publish/bookmark or direct 
access. The main purpose is to hide/protect video urls, secondary is to 
prevent downloading. So users with expired membership can't access course 
anymore or can't send links to other people. I know i can't protect videos 
100%, but i want to hide it for "regular" users. 

So, to make my life easier i hope Vimeo (paid membership) or other services 
should be able to help me. I have few question as Django beginner and 
looking for your help:

1. is my solution fine or i should change something?
2. is Vimeo good choice to serve videos? Do you have any experiences with 
Vimeo?
3. if i insert Vimeo videos to pages, is it somehow protected? Or it's like 
YT videos and anybody can simply download?
4. are there any other problems to be considered?

Many thanks for help or tips!

Re: image not showing on page

[John McClain]

I mean your answer was quite derogatory and if you are not part of the
solution then you are part of the problem

and for your information, I am a learner and I am trying to learn and I
have spent a lot of time on the boards on StackOverflow and elsewhere
including using my inspect tool inside chrome

this is coming through email message so I get a lot of other gibberish in
the inspect tool

while I appreciate you may have the best of intentions by making a
statement like the one you did, I would also suggest it is not helpful. My
"GENIUS" statement was only pointing out the obvious which is what you
stated... if I knew how to use those tools I likely wouldn't be here on
this forum asking for help! So I simply am pointing out that you're the
"master of the obvious" and a genius for (or smartass) for posting such a
comment!

as I stated earlier

IF YOU ARE NOT PART OF THE SOLUTION YOU ARE PART OF THE PROBLEM

Please be more considerate in the future with your post, I think you have
made a conclusion (or assumption) that is not fair to make. You have zero
idea of what I have been doing to this point to try and resolve the problem
on my own. I should not have to put up with the likes of you and your
comments when I am posting requests for guidance or help (neither should
anyone else for that matter)

be kind or get lost!

I'm sorry if it sounded like that. That was not my intention. I was

saying I'm part of.

OK. How was I supposed to know that? You didn't post any output from the 
inspect tool.

Maybe some of that gibberish would help point out where your problem is? 
I'm guessing there's a 404 hidden somewhere there.

I'm not sure I understand. Do you know how to look in the logs or don't you?

Maybe writing something like "I already know how to use the Chrome 
inspect tools, but I'm not sure what to look for. There's a lot of 
gibberish there" would have been a bit more constructive than simply 
calling me "genius".



as I stated earlier

IF YOU ARE NOT PART OF THE SOLUTION YOU ARE PART OF THE PROBLEM



I'm still not sure which problem I'm part of. I definitely cannot see 
I'm part of your problem getting an image to display on your web page, 
so that cannot be it.


Please be more considerate in the future with your post, I think you

resolve the problem on my own. I should not have to put up with the

I will try to be more considerate and I'm sorry that you read my comment 
the wrong way. That was not my intention. I was trying to help you.

I cannot really see how I am the one being rude here...

Re: image not showing on page

[John McClain]

Kasper,

Thanks for clarifying matters...

I think you could have asked for more details or asked for me to provide
those resources so you could evaluate further rather than replying the way
you did.

As far as the inspector goes it is not flagging anything that is useful for
this matter. As I stated the issue is related to an email auth verification
process whereby the path is not working. When google grabs it the path is
interrupted for some reason.

However, I have resolved the issue by removing the django path requirements
and using the direct path to the was s3 location that hosts the image. I am
not sure this is the best practice but it did work for me

I went from this:

style="background-image: img src="{% static 'images/image_name.png'
%};">


to this:

https://alphabetacharlie.s3.amazonaws.com/static/images/image_name.png";>

and it worked

Keep in mind this is only a solution for dealing with the mail routing
issue as I can use normal django syntax within the app itself.

Thanks for your feedback.

Cheers,

John

how to use django template language inside script html tag using django-jsRender

[Yacin Omar]

As I know, there is no way to use Django template language inside 
Javascript block so I searched for a way how to do it, I found a Django app 
on github  called django-jsrender but unfortunately, there isn't enough 
documentation for this app and when I tried to use it I couldn't and this 
is my code:

Re: image not showing on page

[Andréas Kühne]

What I stated earlier is probably your issue:

You have the following:
style="background-image: img src="{% static 'images/image_name.png'
%};">

You see the ";" at the end? The path to your image is then
"images/image_name.png;" <- which is incorrect because of the
extra semicolon.

I would at least start by removing that.

Regards,

Andréas

Re: how to use django template language inside script html tag using django-jsRender

[Antje Kazimiers]

I think you can use some basic template language within a script block like
below. myData is a stringified json object, that worked for me.
antje


  {% if myData %}
var table_data = {{ myData|safe }};
  {% else %}
var table_data = null;
  {% endif %}

multiple constraints not working in the db

[mccc]

Hello,

I'm having issues getting multiple constraints to work (in postgres, if it 
matters).
Here is the Meta:


class Meta:
constraints = [
CheckConstraint(
check=(Q(target_value__gt=0) & ~Q(target_metric=DEFAULT)) |
  (Q(enabled=False) |
   Q(status=IMPORTING) |
   Q(status=IMPORT_FAILURE)),
name="positive_target_value",
)
]


It would seem straightforward enough to me, but it ends up not working.
Here is the generated SQL (pulled from the db itself):
target_value > 0.0::double precision AND NOT target_metric::text = 'DEFAULT'
::text OR enabled = false OR status = 20 OR status = 30

And here is proof that it should actually work (pulled from a django 
console, where the conditions are copied from the migration file):

Folder.objects.filter(models.Q(models.Q(('target_value__gt', 0), 
models.Q(_negated=True, target_metric='DEFAULT')), ('enabled', False), 
('status', 20), ('status', 30), _connector='OR'))
web_1   | Out[5]: ]>
Folder.objects.filter(models.Q(models.Q(('target_value__gt', 0), 
models.Q(_negated=True, target_metric='**SOMETHING DIFFERENT**')), ('enabled', 
False), ('status', 20), ('status', 30), _connector='OR'))
web_1   | Out[7]: , < Folder: 
Folder thisFolderShouldNotHaveBeenCreted>]>


Anybody has any suggestion?
Btw, I also tried switching the first condition with the second one, 
effectively putting the AND at the bottom of the query, but it didn't seem 
to have any effect.

Thanks a lot.
