You are probably requesting the URL without a trailing slash, and have `APPEND_SLASH` set to True (the default) in settings.py, so Django is redirecting to the URL including a slash.

My problem was PREPEND_WWW, when using it in localhost it returns a 301 error, I just created a local settings file and set it PREPEND_WWW = False

In my case, commenting the **SecurityMiddleware** on the `settings.py` file did the trick. I have to say that this only happens when running the `runserver` command (aka. when testing). With Apache it doesn&#39;t falls into the redirect loop.

So for me, it was a combination of the following:
- `SecurityMiddleware` enabled
- `SECURE_SSL_REDIRECT = True`
- Separate Web Server had SSL redirect enabled as well

In that case, the web server already does the redirecting and forwards the request via HTTP to Django, which then redirects again to HTTPS which ends in an infinite loop.

So, in that case, it&#39;s safe to set `SECURE_SSL_REDIRECT = False`.

When using postman everything was working okay but when i was requesting it from the frontend i was getting the 301 error. You are probably missing the trailing slash in the url, i had the same problem and i solved it by adding the slash to the url....


I need to emulate enum type in Javascript and approach seems pretty straight forward:

    var MyEnum = {Left = 1; Right = 2; Top = 4; Bottom = 8}

Now, in C# I could combine those values like this:

    MyEnum left_right = MyEnum.Left | MyEnum.Right

and then I can test if enum has certain value:

    if (left_right &amp; MyEnum.Left == MyEnum.Left) {...}

Can I do something like that in Javascript?

I&#39;m wondering, what is a standard way of updating multiple fields of an instance of a model in django? ... If I have a model with some fields,

    Class foomodel(models.Model):
        field1 = models.CharField(max_length=10)
        field2 = models.CharField(max_length=10)
        field3 = models.CharField(max_length=10)
        ...

... and I instantiate it with one field given, and then in a separate step I want to provide the rest of the fields, how do I do that by just passing a dictionary or key value params? Possible?


In other words, say I have a dictionary with some data in it that has everything I want to write into an instance of that model. The model instance has been instantiated in a separate step and let&#39;s say it hasn&#39;t been persisted yet. I can say `foo_instance.field1 = my_data_dict[&#39;field1&#39;]` for each field, but something tells me there should be a way of calling a method on the model instance where I just pass all of the field-value pairs at once and it updates them. Something like `foo_instance.update(my_data_dict)`. I don&#39;t see any built-in methods like this, am I missing it or how is this efficiently done? 

I have a feeling this is an obvious, RTM kind of question but I just haven&#39;t seen it in the docs.

How to update multiple fields of a django model instance?

I have a django view that returns HTTP 301 on a curl request:

    grapefruit:~ pete$ curl -I http://someurl

 I can&#39;t get the page&#39;s content from curl. However, if I visit the page with a browser, I see the content as expected.

Any ideas?

I&#39;ve got two applications located on two separate computers. On computer A, in the `urls.py` file I have a line like the following: 

    (r&#39;^cast/$&#39;, &#39;mySite.simulate.views.cast&#39;)

And that url will work for both `mySite.com/cast/` and `mySite.com/cast`. But on computer B I have a similar url written out like:

    (r&#39;^login/$&#39;, &#39;mySite.myUser.views.login&#39;)

For some reason on computer B the `url mySite.com/login`/ will work but `mySite.com/login` will hang and won&#39;t direct back to `mySite.com/login/` like it will on computer A. Is there something I missed? Both `url.py` files look identical to me.

I have yet to find a way of setting up Python logging with Django that I&#39;m happy with. My requirements are fairly simple:

* Different log handlers for different events - that is, I want to be able to log to different files
* Easy access to loggers in my modules. The module should be able to find its logger with little effort.
* Should be easily applicable to command-line modules. Parts of the system are stand-alone command line or daemon processes. Logging should be easily usable with these modules.

My current setup is to use a `logging.conf` file and setup logging in each module I log from. It doesn&#39;t feel right. 

Do you have a logging setup that you like? Please detail it: how do you setup the configuration (do you use `logging.conf` or set it up in code), where/when do you initiate the loggers, and how do you get access to them in your modules, etc.

I&#39;m trying to atomically increment a simple counter in Django. My code looks like this:

    from models import Counter
    from django.db import transaction

    @transaction.commit_on_success
    def increment_counter(name):
        counter = Counter.objects.get_or_create(name = name)[0]
        counter.count += 1
        counter.save()

If I understand Django correctly, this should wrap the function in a transaction and make the increment atomic. But it doesn&#39;t work and there is a race condition in the counter update. How can this code be made thread-safe?

I have recently updated my model, added a BooleanField to it however when I do `python manage.py syncdb`, it doesn&#39;t add the new field to the database for the model. How can I fix this ?

In Django&#39;s admin, I want _disable_ the links provided on the &quot;select item to change&quot; page so that users cannot go anywhere to edit the item.  (I am going to limit what the users can do with this list to a set of drop down actions - no actual editing of fields).

I see that Django has the ability to [choose which fields display the link][1], however, I can&#39;t see how I can have **none** of them.  

    class HitAdmin(admin.ModelAdmin):
        list_display = (&#39;user&#39;,&#39;ip&#39;,&#39;user_agent&#39;,&#39;hitcount&#39;)
        search_fields = (&#39;ip&#39;,&#39;user_agent&#39;)
        date_hierarchy = &#39;created&#39;
        list_display_links = [] # doesn&#39;t work, goes to default

Any ideas how to get my object list without any links to edit?

I am running a curl operation on the command line and am having trouble forcing the header to set as XML. I use the -H option to force the Content-Type to be xml, however, once I run the command I can see that the header is sent as urlencoded which is tainting one of the data values that I&#39;m sending. Can someone explain to me why the Content-Type is always reset back to &quot;application/x-www-form-urlencoded&quot; instead of &quot;application/atom+xml&quot;?

I am using this to  retrieve an upload token from YouTube using their API. I have no trouble retrieving an authentication token using a similar command.

    -H Content-Type= text/xml
    --data content=some xml content here

Curl setting Content-Type incorrectly

when retrieving data from a URL using curl, I sometimes (in 80% of the cases) get

**error 18: transfer closed with outstanding read data remaining**

Part of the returned data is then missing. The weird thing is that this does never occur when the CURLOPT_RETURNTRANSFER is set to false, that is the curl_exec function doesn&#39;t return the data but displays the content directly.

What could be the problem? Can I set some of the options to avoid such behaviour?

curl error 18 - transfer closed with outstanding read data remaining

When I use this code:

    $ch = curl_init($url);
    $statuses = curl_exec($ch);
    curl_close($ch);

I am returned what I want, but if I just use that - `$statuses` is echoed out onto the page.

How can I stop this?

I have a cron job setup on one server to run a backup script in PHP that is hosted on another server. 

The command I&#39;ve been using is

    curl -sS http://www.example.com/backup.php

Lately I&#39;ve been getting this error when the Cron runs:

    curl: (52) Empty reply from server

If I go to the link directly in my browser the script runs fine and I get my little backup ZIP file.

What is the curl error 52 &quot;empty reply from server&quot;?

I&#39;m working on setting up credit card processing and needed to use a workaround for CURL. The following code worked fine when I was using the test server (which wasn&#39;t calling an SSL URL), but now when I am testing it on the working server with HTTPS, it&#39;s failing with the error message &quot;failed to open stream&quot;.

    function send($packet, $url) {
      $ctx = stream_context_create(
        array(
          &#39;http&#39;=&gt;array(
            &#39;header&#39;=&gt;&quot;Content-type: application/x-www-form-urlencoded&quot;,
            &#39;method&#39;=&gt;&#39;POST&#39;,
            &#39;content&#39;=&gt;$packet
          )
        )
      );
      return file_get_contents($url, 0, $ctx);
    }

I am building an application (on windows using Dev-C++) and I want it to download a file. I am doing this using libcurl (I have already installed the source code using packman). I found a working example (http://siddhantahuja.wordpress.com/2009/04/12/how-to-download-a-file-from-a-url-and-save-onto-local-directory-in-c-using-libcurl/) but it doesn&#39;t close the file after download is complete. I would like someone to give an example on how to download a file, either in c or c++. Thanks in advance!

I want to store the result of this curl function in a variable, how can I do so?

    #include &lt;stdio.h&gt;
    #include &lt;curl/curl.h&gt;
    
    int main(void)
    {
      CURL *curl;
      CURLcode res;
    
      curl = curl_easy_init();
      if(curl) {
        curl_easy_setopt(curl, CURLOPT_URL, &quot;curl.haxx.se&quot;);
        res = curl_easy_perform(curl);
    
        /* always cleanup */
        curl_easy_cleanup(curl);
      }
      return 0;
    }

thanks, I solved it like this:

    #include &lt;stdio.h&gt;
    #include &lt;stdlib.h&gt;
    #include &lt;curl/curl.h&gt;
    
    function_pt(void *ptr, size_t size, size_t nmemb, void *stream){
        printf(&quot;%d&quot;, atoi(ptr));
    }
    
    int main(void)
    {
      CURL *curl;
      curl = curl_easy_init();
      if(curl) {
        curl_easy_setopt(curl, CURLOPT_URL, &quot;curl.haxx.se&quot;);
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, function_pt);

C libcurl get output into a string

I&#39;m building a Curl web automation app and am having some issue with not getting the desired outcome of my POST action, I am having some trouble figuring out how I can show the full POST request I am sending over (with headers), I have been searching on this but everything that comes up is the response headers, actually I want these too but also the request, which none of the posts I find on google seem to mention..

I know I can display the result of a curl request using something like this (forgive me if my syntax is off, I already shut down my virtual machine with my ide and code to refer to

    
     $result = curl($curl_exect) ;

Anyways, I would greatly appreciate any advice on how to view the full headers, thanks
