Hello and thank your for your help:

 

Task: The customer leaves text and digit (the number of stars) i must display it on the page. The review - link.

 

How i done it:

 

1) Add method to the model:

 

classMention(models.Model):
    mentionn = models.ForeignKey(Step,on_delete=models.CASCADE)
    mention_text = models.TextField()
    mention_digit = models.IntegerField()

defget_star(self):
ifself.mention_digit ==1:
return'<img src="../static/bakot/imagination/starfull.ico">'*1
elifself.mention_digit ==2:
return'<img src="../static/bakot/imagination/starfull.ico">'*2
elifself.mention_digit ==3:
return'<img src="../static/bakot/imagination/starfull.ico">'*3
elifself.mention_digit ==4:
return'<img src="../static/bakot/imagination/starfull.ico">'*4
elifself.mention_digit ==5:
return'<img src="../static/bakot/imagination/starfull.ico">'*5
else:
returnself.mention_digit
  

 

2) Install the method to my template:

 

<divclass="small-12 medium-12 large-6 columns">
<ulclass="menu pdding_h44">
<p>{{ men.get_star|safe }}</p>
</ul>
</div>

 

The problem: It works, but  i know it is very stupied realization. I was trying to do it with with static files, like (below), but it didn't work.

 

return'<img src="{% static "bakot/imagination/starfull.ico" %}">'*3

 

Could someone suggest me the right way of realization this task?

Option (1) would break if you change your STATIC_URL. It's unmaintainable.

Option (2) doesnt work.

 

I'd go with something like:

 

    class Mention(...

        def get_stars(self):

            return "bakot/imagination/starfull.png"

 

And in your template use that:

 

    <img src="{% static mention.get_stars %}" alt="blah">...

 

This keeps static files stuff decoupled from the model (though you still have a filename there, ugh).

 

My final option is doing it PROPERLY, and would consist of creating a custom template tag, and use the staticfile_storage to get the full URL (you'll have to rtfm for both things). This will be more work, but you'll also learn more in the process.
