Re: Django - Pass a model instance specified by template tags to the view

2017-11-09 Thread Adam Simon

I would recommend taking a look at how Jquey does Ajax. It’s a lot simpler
than Django forms. I will post some example code when I get home

Re: Django - Pass a model instance specified by template tags to the view

2017-11-09 Thread Jack

Ok I'm very stuck.  Thought very hard about it but can't see how I can add 
a hidden field into the HTML, and relay the specified instance of the 
hidden field back to the views... or am I completely off about something?

Also in regards to the looped form's.  If you look at my original code, I 
actually do have a  representing a button for each agent.  The 
resulting page looks like this 
 (excuse the bad 
CSS).  I'm not sure if that is what you meant by having a form for each 
agent.

So if I understood you correctly, I do have a separate  input for 
each displayed agent; looped with {% for agent in agent_list %}.  The 
question is, how do I relay the correct agent linked to its 'Send Invite' 
button back to the views?

Re: How do I pass the CSRF token when using a jQuery post

2017-11-09 Thread Tony King


Thanks Gourav,

I have it working now and I can even understand it, which is even better.  
For anyone interested my revised working solution is below.

I'm sure it would be better practice putting the token into the headers as 
described in the documentation and elsewhere but I could not get it to work.


{% load static %}




https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js";>



{% csrf_token %}

{{ hdr1 }}




{% if my_apps_list %}
{% for my_apps in my_apps_list %}





$("#app{{ forloop.counter }}").click( function() {
document.getElementById('hdr_1').innerHTML = 'Hello World!';
$.ajax({
url : "{% url 'launch' %}",
type: "POST",
data: { csrfmiddlewaretoken: document.getElementsByName(
'csrfmiddlewaretoken')[0].value,
appname: '{{ my_apps.app_name }}',
apppath: '{{ my_apps.app_path }}',
appexe: '{{ my_apps.app_exe }}',
appargs: '{{ my_apps.app_args }}',
appusr: '{{ my_apps.app_user }}',
apppwd: '{{ my_apps.app_pwd }}',
applook4: '{{ my_apps.app_wait4 }}',
appdelay: '{{ my_apps.app_delay }}',
appkeys: '{{ my_apps.app_keys }}'},
dataType : "json",
success: function( msg ){
document.getElementById('appstatus').innerHTML = msg;
}
});
});


{% endfor %}






{% else %}
No applications are available.

Re: Django - Pass a model instance specified by template tags to the view

Each form would be generated by a loop; still I would go with the hidden
field.

Look forward to seeing how it goes.

Re: Django - Pass a model instance specified by template tags to the view

2017-11-09 Thread Jack

There will be a lot of agents in the database, so would it violate the DRY 
principle if I were to write a form for each agent?  Plus it'll be super 
time consuming.

I'm going to try the hidden agent.id thing, I never thought about that.  
I'll report back to see if I managed to get it working.

Re: executing python script in html button

2017-11-09 Thread Derek

Hi

Its unlikely anyone on this list will write your code - but the good news 
is that are lots of helpful tutorials from which you can learn to do this; 
for example:

* https://docs.djangoproject.com/en/1.11/intro/tutorial04/
* https://tutorial.djangogirls.org/en/django_forms/
* https://www.simplifiedpython.net/django-forms-tutorial-working-forms/

Its likely though, that you might need to work through some of the other 
material so you can understand how and where forms fit into the overall 
Django approach.

Hope this helps
Derek
