I just read the folowing article and i would like more information about the first method using TemplateColumn. I would like to produce two pseudo columns for edit and delete methods of each record.

edit.html

> <a href="{% url some_url_edit record.pk %}" class="tbl_icon
> edit">Edit</a>

delete.html

> <a href="{% url some_url_del record.pk %}" class="tbl_icon
> delete">Delete</a>

2 pseudo columns that does not exist in DB

class MyTable(tables.Table):
column_edit = tables.TemplateColumn(edit.html) column_delete=tables.TemplateColumn(delete.html)

If that is correct according to the article how record.pk is passed on every template to get the required information about its key?

If you want to edit or delete an object then you'd need to use a model table: 

class MyModelTable(tables.Table):
    name = tables.columns.Column()
    edit = tables.TemplateColumn('<a href='{% url "edit_my_model_instance" record.id %}'>Edit</a>', verbose_name=u'Edit', )    
    delete = tables.TemplateColumn('<a href='{% url "del_my_model_instance" record.id %}'>Delete</a>', verbose_name=u'Delete', )    

    class Meta:
        model = models.MyModel

Notice how we use record.id to pass it the id of each row to the url template tag in order to output the correct edit/delete url.

  • In case we want to display link images instead of link text with verbose_name how this happens? Should we place somewhere a class and how we define it above in this code? – asimkon Apr 26 '16 at 17:30
  • Using the TemplateColumn you can display whatever you want. For example, if instead of the Edit text you want to display an image you can just use `edit = tables.TemplateColumn('', verbose_name=u'Edit', )` – Serafeim Apr 26 '16 at 20:27

i am afraid that your code is a bit faulty as someone must use the following commands to get properly displayed the images inside the columns: edit = tables.TemplateColumn('<a href="{% url "edit_division" record.pk %}"><img src=\'{% load staticfiles %} {% static "images/edit.jpg" %}\' / width="25"></a>',verbose_name=u'Edit',) 

 delete = tables.TemplateColumn('<a href="{% url "delete_division" record.pk %}"><img src=\'{% load  staticfiles %} {% static "images/delete.jpg" %}\' / width="25"></a>',verbose_name=u'Delete',)

I would like to ask if i could use inside tables.py bootstrap css for better rendering of columns and data tables?

  • Yes you can - I think you should add a `class='table'` to your table's `Meta`. – Serafeim Apr 27 '16 at 10:36
  • I have used successfully in my tables.py the following command attrs = {"class":"paleblue"}, but i want to use two classes similar to attrs = {"class":["paleblue","table-responsive"]} for mobile friendly but it does not work ??? thanks – asimkon Apr 28 '16 at 09:19
  • I think that paleblue is different than the bootstrap classes - I recommend using only the "table table-responsive" classes. – Serafeim Apr 28 '16 at 10:00
  • I tried to use attrs = {"class":"table"} in tables.py and i got nothing on rendering. Should i include a css as header in the template and which file. Besides is there a command where i can use many classes together similar to attrs = {"class":["paleblue","table table-responsive"]}. I think paleblue is only a theme class included default inside djnago-tables2. Thanks – asimkon Apr 28 '16 at 11:44
  • Yes, paleblue is the default theme of djagno-tables2, but I think that if you have included the bootstrap.css you'll get the bootstrap styling by adding the class "table". Also, from what I see, django-tables2 provides a special template for bootstrap, check the example here: https://github.com/bradleyayers/django-tables2/blob/214b83dd329a60c607db06a7f15b17ebd64e1de4/example/app/tables.py – Serafeim Apr 28 '16 at 11:53
