Hi,

In one Django App, I've created a simple form. It has URLField, where user
enters FTP url. As soon as user submits the form, I have to download the
file and save it our servers. File size: ~10gb. Need to download securely.

I am new to Django. Any help/resources is highly appreciated. Thank You!

Use ftplib to download the file. It is not completely clear what you mean by
"download securely", but ftplib will handle ftps. If you need sftp,
i.e., ftp over
SSH, use paramiko.

You should also use an offline task processor like Celery, rather than trying to
download a 10GB file in a web request.

Gora

Hi Anand,

Tasks which take significant time such as downloading a file should be kept
out of the normal request-response processing. I suggest using an
asynchronous task queue like Celery <http://www.celeryproject.org/> for
this. Once the form is found to be valid, you can start a Celery task to
download. When the download completes you can inform the user by email or a
polling web page.

Aryn

Hi,

I am currently using Python 3. I have made a basic program which fetches
HTML response from a URL and then parses it to get JS, CSS (using tinyCss2)
and Image GET Requests URLs that the page should make to display properly.

Problem here is that I am not able to get/locate all the requests as some
requests are done by executing JS code. Could anyone suggest how to go
ahead or a better approach?

Best Regards,
Akshay Verma.

Hi Akshay,

It seems that you need to scrape the webpages and execute the JavaScript
somehow. There are several solutions to this. A simple approach is to use
the Chrome Inspector and copy the URLs being accessed by JavaScript.
Another approach will be to use a headless browser like PhantomJS using
Selenium or use Selenium alone as explained in this tutorial
<http://thiagomarzagao.com/2013/11/12/webscraping-with-selenium-part-1/>.

Again, all this might fail if the Javascript content is truly dynamic like
a serverside token. So, good luck! :)

Cheers,
Arun

Message-ID: <CALCtiO56Lk=yB7003L20aku9UXn8b_FAUQcrdo=nHOFnLVqniQ@mail.gmail.com>

Hi,

*models.py*

*def my_func(sender, instance, created, **kwargs):*
*      # do something*
*      instance.status = 'task completed'*
*      instance.save()*

*class MyModel(models.Model):*
*      status = models.CharField(max_length=100, blank=True)*
*      # some code*

*signals.post_save.connect(my_func, sender=MyModel)*


I am using post_save signal to connect to a function.

If a new instance of model is saved, post_save signal connects to my_func.
Once the function is executed, I am updating status of the model.
This is again sending post_save signal which is leading to infinite loop.

I want to execute my_func only once and update status many times.
Does any one know how to do this?

Hi Anand

 I would save *don't* use Django signal. Signals are hard to test and don't
know when they will be executed.

Suggestions
- If post_save function does some work like updating external service which
can take data, use rq or celery.
- You can override django save.

class MyModel(BaseClass):

    def save(self, **kwargs)
       # set all attributes
      # call super class save
      # call function here - blocking call.

1. Why are you doing this using a signal? Signals are best used when
saving of Model1 needs to trigger some action on Model2. If you want to
modify Model1 itself, you're better off doing this inside MyModel::save

2. If you really want to do it this way, put an if condition in my_func
so that instance.save() is called only the first time. It is hard to
give details without knowing the reason why you're doing this. But
something like this would work:

    def my_func(sender, instance, created, **kwargs):
        if instance.status == 'task completed':
            return

        # do something
        instance.status = 'task completed'
        instance.save()

Or even something like this:

    def my_func(sender, instance, created, **kwargs):
        try:
            if instance.in_signal:
                return
        except AttributeError:
            instance.in_signal = True
            # do something
            instance.status = 'task completed'
            instance.save()

Notes on using the post_save signal

1 - Do not use post_save to save the instance that is passed. The
`instance.save` is going to cause a never ending loop.
2 - Use post_save signal to do  things not related to updating the model
being saved. Like updating a related model.
3 - Override the save method of the model to do any changes you need to do
to override the default save.
4 - If you have to use signals in this case (Eg. You cannot edit the models
because they are part of a different library) use the pre_save signal and
just modify the attributes without calling `instance.save()`

Like others have noted, you should override model save.  Another option 
would be to use pre_save.  Just set instance.status and don't call 
instance.save?

I have overrided model save.
Moved couple of functions from models.py to tasks.py which lead to circular
imports.
Instead of importing models at the beginning of file, I've imported them in
the functions.

Thank you @krace, @navin, @pradip :)

Hi,

>From Django 1.7 onwards, the proper way to register signals will be inside
a ready function
<https://docs.djangoproject.com/en/dev/ref/applications/#django.apps.AppConfig.ready>
in the app's configuration object. This is thanks to the App-loading
refactor done in the release.

In your case, as mentioned in the docs, create an myapp/apps.py with :

from django.apps import AppConfig

class MyAppConfig(AppConfig):
    def ready(self):
        MyModel = self.get_model('MyModel')
        signals.post_save.connect(my_func, sender=MyModel)

Also add a line to myapp/__init__.py :

default_app_config = 'myapp.apps.MyAppConfig'

This would eliminate circular imports.

Cheers,
Arun

You can use the inspect module to get this information, e.g., see
http://stackoverflow.com/questions/2654113/python-how-to-get-the-callers-method-name-in-the-called-method

IMHO it is not good design for a module to depend on who is calling
it. If you need that, pass a parameter to __init__

pygtk has pretty decent documentation, which you might want to read carefully:
Please see the right-hand sidebar at http://www.pygtk.org/

>From the tutorial: "The variables and functions that are defined in the PyGTK
module are named as gtk.*. So, you are very likely using functions from pygtk,
even when they are named as gtk.XXX. If you are so inclined, you can look into
the two modules to figure out what is defined where.

Here's another page which kind of summarizes the difference between gtk and
pygtk. If you are into creating UI using gtk, I would suggest using some
wrapper module like wx or QT.

Hi Vimal,

Use rauth python library: https://github.com/litl/rauth

Also have a look at this:

Yes, functionally they are same. I am sorry to have missed out the link :
http://stackoverflow.com/questions/3961397/gtk-and-pygtk-difference.

Internally the calls the same.

Message-ID: <CAMOefuc7ePSozq_sEdomWH1K_fybY0SWGn+CfGLJKZW_HVfWLw@mail.gmail.com>

Hello,
i am new to python. I need to write a function which converts a datastore
data to csv format, which is downloadable. I researched upon the topic over
google, got few and less info on it. The code till now is below:

def calllog_csv(self):
        from collections import defaultdict
        date = datetime.strptime('01/01/2014', '%m/%d/%Y')
        qry = CallLog.query().filter(CallLog.created >= date,
CallLog.created <= datetime.now()).fetch()
        columns = defaultdict(qry)
        log.debug("query===>" + str(columns))
        with open('calllog.csv', 'w') as csv_log:
            reader = csv.DictReader(csv_log)
            for row in reader:
                for (k, v) in row.items():
                    columns[k].append(v)
        log.debug("columns== from==>" + str(columns['from']))
        return columns

Tell me where i am wrong, or am i right? any suggestions would be helpfull.
Thank you all in advance

Would you be kind enough to explain how this code snippet relates to
the description
of what you wanted the code to do? It seems to be cut-and-pasted from somewhere
else, and I cannot see how it is relevant. What in the world is "CallLog"?

I think with datastore, you meant to say 'Google App Engine Datastore'... ?
If this is the case, please read API details available at:
https://developers.google.com/appengine/docs/python/datastore/

This would help you extracting data out of datastore.

Thanks,

too. But distances matter. Companies please avoid -- there is not enough

Freelancers with about 20-40 hours of spare time at least a month, please

Hi Vimal,

> I need to write a function which converts a datastore data to csv format,
which is downloadable.

Your code seems to reading a CSV file rather than writing to it. Use a
DictWriter
rather than a DictReader.

But if you need to make it downloadable via a browser, then you need to use
a web framework like Django. Check out the CSV output section
<https://docs.djangoproject.com/en/dev/howto/outputting-csv/> from Django
docs.

Regards,
Arun
