  • Unit testing with django-celery?

    - by Jason Webb
    I am trying to come up with a testing methodology for our django-celery project. I have read the notes in the documentation, but it didn't give me a good idea of what to actually do. I am not worried about testing the tasks in the actual daemons, just the functionality of my code. Mainly I am wondering: How can we bypass task.delay() during the test (I tried setting CELERY_ALWAYS_EAGER = True but it made no difference)? How do we use the test settings that are recommended (if that is the best way) without actually changing our settings.py? Can we still use manage.py test or do we have to use a custom runner? Overall any hints or tips for testing with celery would be very helpful.

  • How do I set a default page in Pylons?

    - by Evgeny
    I've created a new Pylons application and added a controller ("main.py") with a template ("index.mako"). Now the URL http://myserver/main/index works. How do I make this the default page, ie. the one returned when I browse to http://myserver/ ? I've already added a default route in routing.py: def make_map(): """Create, configure and return the routes Mapper""" map = Mapper(directory=config['pylons.paths']['controllers'], always_scan=config['debug']) map.minimization = False # The ErrorController route (handles 404/500 error pages); it should # likely stay at the top, ensuring it can always be resolved map.connect('/error/{action}', controller='error') map.connect('/error/{action}/{id}', controller='error') # CUSTOM ROUTES HERE map.connect('', controller='main', action='index') map.connect('/{controller}/{action}') map.connect('/{controller}/{action}/{id}') return map I've also deleted the contents of the public directory (except for favicon.ico), following the answer to http://stackoverflow.com/questions/1279403/default-route-doesnt-work Now I just get error 404. What else do I need to do to get such a basic thing to work?

  • Run web.py as daemon.

    - by mamcx
    I have a simple web.py program to load data. In the server I don't want to install apache or any webserver. I try to put it as a background service with http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/ And subclassing: (from http://www.jejik.com/files/examples/daemon.py) class Daemon: def start(self): """ Start the daemon """ ... PID CHECKS.... # Start the daemon self.daemonize() self.run() #My code class WebService(Daemon): def run(self): app.run() if __name__ == "__main__": if DEBUG: app.run() else: service = WebService(os.path.join(DIR_ACTUAL,'ElAdministrador.pid')) if len(sys.argv) == 2: if 'start' == sys.argv[1]: service.start() elif 'stop' == sys.argv[1]: service.stop() elif 'restart' == sys.argv[1]: service.restart() else: print "Unknown command" sys.exit(2) sys.exit(0) else: print "usage: %s start|stop|restart" % sys.argv[0] sys.exit(2) However, the web.py software not load (ie: The service no listen) If I call it directly (ie: No using the daemon code) work fine.

  • How can I plot NaN values as a special color with imshow in matplotlib?

    - by Adam Fraser
    example: import numpy as np import matplotlib.pyplot as plt f = plt.figure() ax = f.add_subplot(111) a = np.arange(25).reshape((5,5)).astype(float) a[3,:] = np.nan ax.imshow(a, interpolation='nearest') f.canvas.draw() The resultant image is unexpectedly all blue (the lowest color in the jet colormap). However, if I do the plotting like this: ax.imshow(a, interpolation='nearest', vmin=0, vmax=24) --then I get something better, but the NaN values are drawn the same color as vmin... Is there a graceful way that I can set NaNs to be drawn with a special color (eg: gray or transparent)?

  • How come you cannot catch Code Contract exceptions?

    - by Finglas
    System.Diagnostics.Contracts.ContractException is not accessiable in my test project. Note this code is purely myself messing around with my shiney new copy of Visual Studio, but I'd like to know what I'm doing wrong. I'm using the professional edition of VS, therefore I do not have static checking. In order to still use code contracts (which I like) I figured the only way my method can work is to catch the exception that is thrown at runtime, but I'm not finding this possible. TestMethod [TestMethod, ExpectedException(typeof(System.Diagnostics.Contracts.ContractException))] public void returning_a_value_less_than_one_throws_exception() { var person = new Person(); person.Number(); } Method public int Number() { Contract.Ensures(Contract.Result<int>() >= 0); return -1; } Error Error 1 'System.Diagnostics.Contracts.ContractException' is inaccessible due to its protection level.

  • Difference between URLLIB2 call in IDLE and from Django?

    - by danspants
    The following piece of code works as expected when running in a local install of django apache 2.2 fx = urllib2.Request(f); fx.add_header('User-Agent','Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.19 (KHTML, like Gecko) Chrome/1.0.154.36 Safari/525.19'); url_opened = urllib2.urlopen(fx); However when I enter that code into IDLE on the same machine I get the following error: url_opened = urllib2.urlopen(fx); File "C:\Python25\lib\urllib2.py", line 124, in urlopen return _opener.open(url, data) File "C:\Python25\lib\urllib2.py", line 387, in open response = meth(req, response) File "C:\Python25\lib\urllib2.py", line 498, in http_response 'http', request, response, code, msg, hdrs) File "C:\Python25\lib\urllib2.py", line 425, in error return self._call_chain(*args) File "C:\Python25\lib\urllib2.py", line 360, in _call_chain result = func(*args) File "C:\Python25\lib\urllib2.py", line 506, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) HTTPError: HTTP Error 407: Proxy Authentication Required Any ideas?

  • Finding inline style with lxml.cssselector

    - by ropa
    New to this library (no more familiar with BeautifulSoup either, sadly), trying to do something very simple (search by inline style): <td style="padding: 20px">blah blah </td> I just want to select all tds where style="padding: 20px", but I can't seem to figure it out. All the examples show how to select td, such as: for col in page.cssselect('td'): but that doesn't help me much.

  • Passing a non-iterable to list.extend ()

    - by JS
    Hello, I am creating a public method to allow callers to write values to a device, call it write_vals() for example. Since these values will by typed live, I would like to simplify the user's life by allowing them type in either a list or a single value, depending on how many values they need to write. For example: write_to_device([1,2,3]) or write_to_device(1) My function would like to work with a flat list, so I tried to be clever and code something like this: input_list = [] input_list.extend( input_val ) This works swimmingly when the user inputs a list, but fails miserably when the user inputs a single integer: TypeError: 'int' object is not iterable Using list.append() would create a nested list when a list was passed in, which would be an additional hassle to flatten. Checking the type of the object passed in seems clumsy and non-pythonic and wishing that list.extend() would accept non-iterables has gotten me nowhere. So has trying a variety of other coding methods. Suggestions (coding-related only, please) would be greatly appreciated.

  • How do I do this Database Model in Django?

    - by alex
    Django currently does not support the "Point" datatype in MySQL. That's why I created my own. class PointField(models.Field): def db_type(self): return 'Point' class Tag(models.Model): user = models.ForeignKey(User) utm = PointField() As you can see, this works, and syncdb creates the model fine. However, my current code calculates a length between two Points using raw SQL. cursor.execute("SELECT user_id FROM life_tag WHERE\ (GLength(LineStringFromWKB(LineString(asbinary(utm), asbinary(PointFromWKB(point(%s, %s)))))) < 55)... This says: Select where the length between the given point and the table point is less than 55. How can I do this with Django instead of RAW SQL? I don't want to do cursors and SELECT statements anymore. How can I modify the models.py in order to do this?

Is there something wrong with my code?

  • combining two select statements to return one result

    - by DalivDali
    I need to combine the results for two select queries from two view tables, from which I am performing calculations. Perhaps there is an easier way to perform a query using if...else - any pointers? Essentially I need to divide everything by 'ar.time_ratio' under the condition in sql query 1, and ignore that for query 2. SELECT gs.traffic_date, gs.domain_group, gs.clicks/ar.time_ratio as 'Scaled_clicks', gs.visitors/ar.time_ratio as 'scaled_visitors', gs.revenue/ar.time_ratio as 'scaled_revenue', (gs.revenue/gs.clicks)/ar.time_ratio as 'scaled_average_cpc', (gs.clicks)/(gs.visitors)/ar.time_ratio as 'scaled_ctr', gs.average_rpm/ar.time_ratio as 'scaled_rpm', (((gs.revenue)/(gs.visitors))/ar.time_ratio)*1000 as "Ecpm" FROM group_stats gs, v_active_ratio ar WHERE ar.group_id=gs.domain_group and SELECT gs.traffic_date, gs.domain_group, gs.clicks, gs.visitors, gs.revenue, (gs.revenue/gs.clicks) as 'average_cpc', (gs.clicks)/(gs.visitors) as 'average_ctr', gs.average_rpm, ((gs.revenue)/(gs.visitors))*1000 as "Ecpm" FROM group_stats gs, v_active_ratio ar where not ar.group_id=gs.domain_group

  • Help with parsing lxml

    - by Casey
    Hi To implement a college project, I need to handle XML files. For this I choose lxml after doing some research. However I can't seem to find some nice tutorial to help me get started. I can't choose most specifically which type of parsing I need to use. My XML files don't have that much data but speed is main concern, not memory. Can anyone point me to some tutorial that would help me or some book that I can lookup? I have already tried the tutorial on lxml site but that didn't help me much. Is there some small application I can look up to get a hang of parsing XML with lxml

  • Is it possible to implement a GC.GetAliveInstancesOf<T>() (for use in debugging)?

    - by Omer Raviv
    Hi, I know this was answered before, but I'd like to pose a somewhat different question. Is there any conceivable way to implement GC.GetAliveInstancesOf(), that can be evaluated in Visual Studio Debug Watch window? Sasha Goldstein shows one solution in this article, but it requires every class you want to query inherit from a specific base class. I'll emphasize that I only want to use this method during debugging, so I don't care that the GC may change an object's address in memory during runtime. One idea might be to somehow harness the !dumpheap –type command of SOS, and do some magic trick to create a temporary variable and have it point out to the memory address printed by SOS. Does anyone have a solution that works?

  • Catching typos in scripting languages

  • Why does ASP.NET web site reference assembly from GAC, when adding local reference?

    - by Konstantin
    When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file. Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.

  • Real-time data on webpage with jQuery

    - by Steven Hepting
    I would like a webpage that constantly updates a graph with new data as it arrives. Regularly, all the data you have is passed to the page at the beginning of the request. However, I need the page to be able to update itself with fresh information every few seconds to redraw the graph. Background The webpage will be similar to this http://www.panic.com/blog/2010/03/the-panic-status-board/. The data coming in will temperature values to be graphed measured by an Arduino and saved to the Django database (this part is already complete). Update It sounds as though the solution is to use the jQuery.ajax() function ( http://api.jquery.com/jQuery.ajax/) with a function as the .complete callback that will schedule another request several seconds later to a URL that will return the data in JSON format. How can that method be scheduled? With the .delay() function?

I have some experience toying around with django and the primary reason I am switching to a zope-based framework is ZPT and also needing to occasionally do things with Plone. Both seem to be well run projects I am mainly wondering which would have the better learning overlap with Plone? Thanks in advance!

Bob decides to not eat. Jimmy Foo decides to eat. How can I create a parser for the decides to eat line? If I create my name parser naively, meaning with alphabetic characters plus space characters, then it will match the entire line.

  • CSRF error when trying to log onto Django admin page with w3m on Emacs23

Request aborted. Help Reason given for failure: No CSRF or session cookie. ... Is there a way that I could get w3m to work with my admin page? I am not sure if the problem lies with the way the admin is set up on Django or with the Emacs or w3m settings.

  • Splitting only long words in string

    - by owca
    I have some random string, let's say : s = "This string has some verylongwordsneededtosplit" I'm trying to write a function trunc_string(string, len) that takes string as argument to operate on and 'len' as the number of chars after long words will be splitted. The result should be something like that str = trunc_string(s, 10) str = "This string has some verylongwo rdsneededt osplit" For now I have something like this : def truncate_long_words(s, num): """Splits long words in string""" words = s.split() for word in words: if len(word) > num: split_words = list(words) After this part I have this long word as a list of chars. Now I need to : join 'num' chars together in some word_part temporary list join all word_parts into one word join this word with the rest of words, that weren't long enough to be splitted. Should I make it in somehow similar way ? : counter = 0 for char in split_words: word_part.append(char) counter = counter+1 if counter == num And here I should somehow join all the word_part together creating word and further on
