Re: Database Modeling Help - Relating Instance Fields to Instance Fields
I figured it out, I think.
If I create an intermediary table like this:
class PatchConnection(models.Model):
connection = models.ForeignKey(Connection)
content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
object_id = models.PositiveIntegerField()
content_object = GenericForeignKey('content_type', 'object_id')
Then the PatchPoint model fields would be ForeignKey relations to
PatchConnections.
I guess writing out the question helped me to figure it out.
Thanks,

Database Modeling Help - Relating Instance Fields to Instance Fields
I'm working on an A/V Cable and Equipment management project and have run into an issue. The application is functioning as designed, but I'd like to add another feature that keeps track of connections between equipment and cables. Since the app is working as is, I'd like to fit this feature in the current schema. Here's a really basic models.py that I wrote to describe the problem.

Re: looking for an apache/system admin master
Thanks for the reply. I had no idea things like munin or graphite existed. Graphite looks really interesting. I'm honestly worried because I feel that since I'm new to setting up Apache servers that I can make a mistake that may be detrimental to my company's network and information. Our system is monitored by an external IT company, so that puts me slightly more at ease, but I still don't feel too comfortable about my current config. I added the two suspect IP addresses to exclude in the virtual host definition. This is more of an Apache config issue, so I won't continue it on the list but if there is anyone in the NYC area that would be willing to help for this one-off config, we can discuss rates etc off list.

looking for an apache/system admin master
I've been using windows/django1.4/apache2.2 for a couple intranet apps and it has been working well. I recently had our admin open up a port in our firewall to deploy another app publicly. We weren't using the app and there were issues when testing, since both the admin and myself are newbies to deploying publicly with Apache with SSL. So we left the server as is and tested UX for this app on an external host. We installed a new system wide firewall last week which the admin thought would help with our issues so I went to do some server prep today to bring the app on an internal server again. A check of the access logs found a specific external IP address hitting the server every 1/4 second with strange URLs that look to be commonly used php urls since June 7,2013. It has been getting hit for DAYs and I just wasn't monitoring the server. Each of the requests either 302'd or 404'd and there are thousands of them. I stopped the server, and sent an email to the admin to close that port down. Since neither I nor the system admin know much about deploying, is there anywhere I can look to hire someone to help get this app deployed safely? Our policies require SSL and we are willing to use other OS or servers, we just need someone who knows what they are doing. We are in the NYC vicinity.

Re: Problem with csrf
I'm not sure it absolutely needs fixing. There may be times that you don't need to use an HttpRequest but may need csrf protection in a view. Maybe? I don't know, but at least maybe under step 3.1 they should make the first word RequestContext a link to https://docs.djangoproject.com/en/dev/ref/templates/api/#subclassing-context-requestcontext for people working off the docs like you did.

Complex(for me) queryset comparisons
I am having an issue coming up with a way to analyze data that I've been
collecting. I would rather not change my model definition at this point,
but I am open to suggestions.
A Bundle is a group of audio/video/AC cables that are taped together in our
warehouse to our client's specification. We build hundreds of these per
month and would like to analyze the most common Bundles that we create to
increase efficiency.
Here is my model definition:
class Bundle(models.Model):
name = models.CharField(max_length=50)
length = models.CharField(max_length=50, choices=LENGTH)
created = models.DateField(auto_now=True)
archived = models.BooleanField(default=False)
class Cable(models.Model):
cable_type = models.CharField(max_length=50, choices=CABLE_TYPES)
origin_cable_connector = models.CharField(
max_length=50, choices=CONNECTORS, verbose_name='Taped End')
destination_cable_connector = models.CharField(
max_length=50, choices=CONNECTORS, verbose_name='Non-taped End')
bundle = models.ForeignKey('Bundle')
Some examples for the constants:
CABLE_TYPES: powercon, 19pr, XLR
CONNECTORS: powercon(blue), powercon(grey), G3(male), G3(female),
XLR(Male), XLR(Female),
LENGTH: 25ft, 150ft, 200ft
If I wanted to know the number of times a similar Bundle is created, I
wanted to use something like:
repeated_sets = {}
all_cable_sets = [list(sorted(b.cable_set.all())) for b in
Bundle.objects.all()]
for set in all_cable_sets:
occurences = all_cable_sets.count(set)
print occurences
if occurences > 1:
if set not in repeated_sets:
repeated_sets[set] = occurences
This doesn't work because each set belongs to a different bundle, so they
are all unique and occurences never goes greater than 1.
I would also like to know the lengths of these similar Bundles and the
number of times identical bundles were created where the cable_sets are all
the same and their parent Bundle's length is the same. I figured I should
attempt the simpler query first without the length, and add length later by
iterating through the repeated_sets dictionary and querying for each
cable_set's parent Bundle and generating a new dictionary out of that.
Should I be approaching this from a different angle? Is there a nice
Django way of making these comparisons and counts?
Thank you,
-Matt

Re: Point System in django
A quick google didn't turn up any packages for your specific case, but you may not want to use a pre-built solution. Amirouche wanted some more information about how you plan on implementing the project. Here's a simple concept: It seems that you would want to customize the standard User model and add an integer field "Points" to it with default value=0. When the User purchases these fictitious points, you would increment their associated Points value by whatever they paid for. Then when the User is on the site and logged in, you can use Javascript to send an asynchronous request to the server when the Play button is pressed on the page. Since the user is logged in, it's instance is available in the context that was sent through in the AJAX request. You would then be able to subtract the corresponding point value from that User's Points field. Obviously my description has flaws: you need to be careful with the Javascript so the User doesn't click the Play button multiple times, you need to set rules in the User model to not allow negative Point values, not allow the user to press the Play the button if they don't have enough Points, etc. On Wednesday, June 12, 2013 1:38:45 PM UTC-4, coded kid wrote: > > How do you mean?

Re: Problem with csrf
You are correct in assuming that your first view using render_to_response
shouldn't work without sending a RequestContext in.
A much cleaner way is just to use the render function.
https://docs.djangoproject.com/en/dev/topics/http/shortcuts/#render
which takes a lot of typing out of the typical render_to_response with
RequestContext.

Re: Controlling GPIO on rasPi, need help with Refreshing switch status without reloading page via jquery
I think you are on the right track with the jquery setup for handling the
submission of the form. What you need to implement here is an AJAX form.
I would do something like this, although I don't necessarily know what I'm
doing:
$(document).ready(function () {
var form = $("#gpio_form")
var button = $("#{{pin1.PinID}}")
form.submit(function(e) {
e.preventDefault()
$.get("url that points to your AJAX view/",
form.serialize(), function(message){
if (message == 'true'){
button.attr('value', '1')
} // end if message is true
if (message == 'false'){
button.attr('value', '0')
}// end if message is false
});// end get call
});// end form submit
});// end doc ready
So instead of your current view, I would use a dedicated URL and view that
handles the AJAX GET request. GET vs. POST request conventions aside, for
the point of instruction, $.get is easier to use, but is not semantically
correct.
The view that handles the button value change would look like something
like this:
def button_check(request):
try:
#something that checks the GET for button status
if request.GET['button'] == 1:
result = True
else:
result = False
except:
result = False
message = json.dumps({'result':result})
return HttpResponse(message, mimetype="application/json")
Sorry for the garbage code, but hopefully this will help describe how to
make an AJAX form and get you most of the way there. If you want to
contact me off list, I am willing to help since I'm interested in Django on
the RaspberryPi

Re: Editable Tables
Try DHTMLX Grid. I use it solely for the editable grid feature. It took a little while to style it so it fits with my site, but as far as simple AJAX editable grids, I couldn't find an better one.

Re: New to Django, having difficulty creating first app. PLEASE HELP!
Glad you are trying out Django. That error is telling you what's wrong The directory that you are in does not include the file "manage.py". Depending on your operating system, when you get this error, get the contents of the directory(windows, type dir and press enter) if the outputted list doesn't include "manage.py", then you are not in the outer mysite directory. You most likely did not "change into the outer mysite directory". So from that point in the tutorial, type cd .. and press enter, and that should be the outer directory. just to be sure, check the contents of the directory you are in by typing "dir". Sorry if that answer is a little too basic and you already know all that, but I wanted to offer the simplest troubleshooting options first.

RES: Django-tables2
If you make that column a regular Column does it render properly? If not then confirm that you define the column exactly as it is spelled in your models.py(case and all). Once it renders properly as a regular Column, then try changing to a LinkColumn. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django-tables2
Here's an example of one of my tables.
class NeedsTable(tables.Table):
needQuantity = tables.Column()
prod_id = tables.Column()
description = tables.LinkColumn('needsdetail', args=[A('pk')])
department = tables.Column()
order = tables.Column()
priority = tables.Column(accessor='order.event.priority')
show = tables.Column(accessor='order.event.name')
preppedQuantity = tables.Column()
prepdate = tables.Column()
class Meta:
order_by = 'priority'
attrs = {'class': 'general_table'}
URLS.py -
url(r'^qcarea/needs/detail/(?P\d+)/$', 'needs.views.needsdetail',
name='needsdetail')
LinkColumn uses reverse() to get its view and you use the Accessor(A) to
pass the pk to the args of the reverse call. This means that you must name
your URL in your urls.py.
In your example, I can't quite figure out what you are attempting with the
TemplateColumn. To me it seems like you need to create two link columns.
Good Luck

Re: Django-tables2
It is just a very easy way to create html tables with one simple template tag that have features like sorting by column, easy, quick css etc. without using javascript at all. There are times when this is easier than creating a table and customizing it. I use it for general tables that don't need any ajax features. Although I've lately been creating manual tables and using the "tablesorter.js" to handle quick sorting.

Django-tables2
Your answer is LinkColumn instead of TemplateColumn. You can pass Args and kwargs with this in your table. I'll post an example of this when I get home. It's quite simple.
