It doesn't seem to take affect for some reason. Any clue of what might be the problem? Do i have to do a sync db ?

  • [Django] How do I filter the choices in a ModelForm that has a CharField with the choices attribute

    - by nubela
    I understand I am able to filter queryset of Foreignkey or Many2ManyFields, however, how do I do that for a simple CharField that is a Select Widget (Select Tag). For example: PRODUCT_STATUS = ( ("unapproved", "Unapproved"), ("approved", "Listed"), #("Backorder","Backorder"), #("oos","Out of Stock"), #("preorder","Preorder"), ("userdisabled", "User Disabled"), ("disapproved", "Disapproved by admin"), ) and the Field: o_status = models.CharField(max_length=100, choices=PRODUCT_STATUS, verbose_name="Product Status", default="approved") Suppose I wish to limit it to just "approved" and "userdisabled" instead showing the full array (which is what I want to show in the admin), how do I do it? Thanks!

  • How should I use try...except while defining a function?

    - by SpawnCxy
    Hi all, I find I've been confused by the problem that when I needn't to use try..except.For last few days it was used in almost every function I defined which I think maybe a bad practice.For example: class mongodb(object): def getRecords(self,tname,conditions=''): try: col = eval("self.db.%s" %tname) recs = col.find(condition) return recs except Exception,e: #here make some error log with e.message What I thought is ,exceptions may be raised everywhere and I have to use try to get them. And my question is,is it a good practice to use it everywhere when defining functions?If not are there any principles for it?Help would be appreciated! Regards

  • TypeError: object not callable when making instance

    - by TSM
    I've searched around other threads with similar questions, but I'm not finding the answer. Basically, I have a class: import Android_Class class Android_Revision(object): def __init__(self): # dict for storing the classes in this revision # (format {name : classObject}): self.Classes = {} self.WorkingClass = Android_Class() self.RevisionNumber = '' def __call__(self): print "Called" def make_Class(self, name): newClass = Android_Class(name) self.Classes.update({name : newClass}) self.WorkingClass = newClass def set_Class(self, name): if not(self.Classes.has_key(name)): newClass = Android_Class(name) self.Classes.update({name : newClass}) self.WorkingClass = self.Classes.get(name) I'm trying to make an instance of this class: Revision = Android_Revision() and that's when I'm getting the error. I'm confused because I have another situation where I'm doing almost the exact same thing, and it's working fine. I can't figure out what differences between the two would lead to this error. Thanks.

  • Looking for a better alternative to linklabels

    - by user986086
    Please see the two long linklabels below (please ignore the black lines above) Linklabels' length is made dynamically during runtime, and as seen, could be that it's too long and overlapping other text we have (there is another text where you see 'Differences'). My questions are: a) Can I limit the maximum length of a linklabel? b) Is that possible to use a scrollbar with a linklabel (or any similar control) in case that it's too long? e.g. setting it to 200 pixels, and in case it's longer, the user has to scroll the horizontal scroller and see end of the text. I'm using VB.NET on Visual Studio 2008 THANK YOU

  • Class views in Django

    - by Sebastjan Trepca
    Django view points to a function, which can be a problem if you want to change only a bit of functionality. Yes, I could have million keyword arguments and even more if statements in the function, but I was thinking more of an object oriented approach. For example, I have a page that displays a user. This page is very similar to page that displays a group, but it's still not so similar to just use another data model. Group also has members etc... One way would be to point views to class methods and then extend that class. Has anyone tried this approach or has any other idea?

  • Trouble with SVN and Filename 'changes'.

    - by Stacey
    I am programming in Visual Studio 2010, using TortiseSVN and VisualSVN as my client to connect to SVN repositories. I am having a bit of a frequent problem though with the whole SVN thing in general. One thing that keeps cropping up is that if I make changes to files - namely filenames, or move them to new folders, etc, I end up getting all kinds of conflicts with the repository and it just causes all sorts of strange errors. I understand the importance of version control and check-in/check-out access like this, but what do most of you do to deal with this kind of thing? I mean, I've tried doing the whole 'Remove from Subversion', change my file, then 'Add to Subversion' thing, and it just doesn't seem to do the job very well. This is especially frustrating when working on web projects where filenames can change very frequently as a project evolves and becomes multifaceted. Are there any standard ways to deal with this kind of thing, or is it just one of the flaws of SVN in general?

  • PGU HTML Renderer can't render most sites

    - by None
    I am trying to make a web browser using pygame. I am using PGU for html rendering. It works fine when I visit simple sites, like example.com, but when I try and load anything more complex that uses an html form, like google, I get this error: UnboundLocalError: local variable 'e' referenced before assignment I looked in the PGU html rendering file and found this code segment: def start_input(self,attrs): r = self.attrs_to_map(attrs) params = self.map_to_params(r) #why bother #params = {} type_,name,value = r.get('type','text'),r.get('name',None),r.get('value',None) f = self.form if type_ == 'text': e = gui.Input(**params) self.map_to_connects(e,r) self.item.add(e) elif type_ == 'radio': if name not in f.groups: f.groups[name] = gui.Group(name=name) g = f.groups[name] del params['name'] e = gui.Radio(group=g,**params) self.map_to_connects(e,r) self.item.add(e) if 'checked' in r: g.value = value elif type_ == 'checkbox': if name not in f.groups: f.groups[name] = gui.Group(name=name) g = f.groups[name] del params['name'] e = gui.Checkbox(group=g,**params) self.map_to_connects(e,r) self.item.add(e) if 'checked' in r: g.value = value elif type_ == 'button': e = gui.Button(**params) self.map_to_connects(e,r) self.item.add(e) elif type_ == 'submit': e = gui.Button(**params) self.map_to_connects(e,r) self.item.add(e) elif type_ == 'file': e = gui.Input(**params) self.map_to_connects(e,r) self.item.add(e) b = gui.Button(value='Browse...') self.item.add(b) def _browse(value): d = gui.FileDialog(); d.connect(gui.CHANGE,gui.action_setvalue,(d,e)) d.open(); b.connect(gui.CLICK,_browse,None) self._locals[r.get('id',None)] = e I got the error in the last line, because e wasn't defined. I am guessing the reason for this is that the if statement that checks the type of the input and creates the e variable didn't match anything. I added a line to print the _type variable and I got 'hidden' when i tried google and apple. Is there any way to render form items that have the type 'hidden' with PGU?

  • How can I load an MP3 or similar music file for display and anaysis in wxWdigets?

    - by Jon Cage
    I'm developing a GUI in wxPython which allows a user to generate sequences of colours for some toys I'm building. Part of the program needs to load an MP3 (and potentially other formats further down the line) and display it to the user. That shuold be sufficient to get started but later I'd like to add features like identifying beats and some crude frequency analysis. Is there any simple way of loading / understanding an MP3's contents to display a plot of it's amplitudes to the screen using wxWidgets? I later intend to port to C++/wxWidgets for speed and to avoid having to distribute wxPython.

  • Counter variable for class

    - by George
    I am having problem getting this piece of code to run. The class is Student which has a IdCounter, and it is where the problem seems to be. (at line 8) class Student: def __init__(self): # Each student get their own student ID idCounter = 0 self.gpa = 0 self.record = {} # Each time I create a new student, the idCounter increment idCounter += 1 self.name = 'Student {0}'.format(Student.idCounter) classRoster = [] # List of students for number in range(25): newStudent = Student() classRoster.append(newStudent) print(newStudent.name) I am trying to have this idCounter inside my Student class, so I can have it as part of the student's name (which is really an ID#, for example Student 12345. But I have been getting error. Traceback (most recent call last): File "/Users/yanwchan/Documents/test.py", line 13, in <module> newStudent = Student() File "/Users/yanwchan/Documents/test.py", line 8, in __init__ idCounter += 1 UnboundLocalError: local variable 'idCounter' referenced before assignment I tried to put the idCounter += 1 in before, after, all combination, but I am still getting the referenced before assignment error, can you explain to me what I am doing wrong? Thank you Edit: Provided the full code I have

  • Is it possibile to modify a link value with Beautifulsoup without recreating the all link?

    - by systempuntoout
    Starting from an Html input like this: <p> <a href="http://www.foo.com" rel="nofollow">this is foo</a> <a href="http://www.bar.com" rel="nofollow">this is bar</a> </p> is it possible to modify the <a> node values ("this i foo" and "this is bar") adding the suffix "PARSED" to the value without recreating the all link? The result need to be like this: <p> <a href="http://www.foo.com" rel="nofollow">this is foo_PARSED</a> <a href="http://www.bar.com" rel="nofollow">this is bar_PARSED</a> </p> And code should be something like: from BeautifulSoup import BeautifulSoup soup = BeautifulSoup(html) for link_tag in soup.findAll('a'): link_tag.string = link_tag.string + '_PARSED' #This obviously does not work

  • Dynamically customize django admin columns ?

    - by tomjerry
    Is it possible to let the users choose / change dynamically the columns displayed in a object list in Django administration ? Things can surely be implemented "from scratch" by modifying the 'change_list.html' template but I was wondering if somebody has already had the same problem and/or if any django-pluggin can do that. Thanks in advance,

  • recursive cumulative sums

    - by user1816377
    I need to write a program that compute cumulative sums from a list of numbers with def but ONLY with recursion. I did it, but now I need to write the same program without using the method sum, but no success so far. Any idea? my code: def rec_cumsum(numbers): ''' Input: numbers - a list of numbers, Output: a list of cumulative sums of the numbers''' if len(numbers)==0: return numbers return rec_cumsum(numbers[:-1])+ [sum(numbers)] input: 1 [1,2,3] 2 [2, 2, 2, 3] output: 1 [1,3,6] 2 [2, 4, 6, 9]

  • How to quickly parse a list of strings

    - by math
    If I want to split a list of words separated by a delimiter character, I can use >>> 'abc,foo,bar'.split(',') ['abc', 'foo', 'bar'] But how to easily and quickly do the same thing if I also want to handle quoted-strings which can contain the delimiter character ? In: 'abc,"a string, with a comma","another, one"' Out: ['abc', 'a string, with a comma', 'another, one'] Related question: How can i parse a comma delimited string into a list (caveat)?

  • SqlAlchemy hangs after adding record in MS SQL

    - by Patrick
    I'm running SQLAlchemy on Jython and trying to connect to a MS SQL database using jTDS with windows authentication. I can query and delete just fine but when I try to insert new values it will hang when I commit. int 'before add' session.add(newVal) print 'after add' session.commit() print 'after commit' I see the first two print statements but not the last. My CPU maxes out and I can't even query the table directly using the MS SQL Management Studio. When I kill the Jython java process I can query again but the new values haven't been added. Strangely enough I can insert values directly using an SQL command: insert_sql = "INSERT INTO my_table (my_value) VALUES ('test_value')" session.execute(insert_sql) session.commit() Any ideas what I'm doing wrong?

  • How to break a loop when inputting unspecified raw_input?

    - by user1874510
    I want to write an interface using a while loop and raw_input. My code looks like this: while True: n = raw_input("'p' = pause, 'u' = unpause, 'p' = play 's' = stop, 'q' = quit) if n.strip() == 'p': mp3.pause() if n.strip() == 'u': mp3.unpause() if n.strip() == 'p': mp3.play() if n.strip() == 's': mp3.stop() if n.strip() == 'q': break But I want it to break if I input anything that isn't specified in the raw_input. if not raw_input: break Returns and IndentationError: unindent does not match any outer indentation level. if not raw_input: break Does not return any error but doesn't work as I want it to. As far as I know, it does nothing at all. Also, if there's a cleaner way to write my loop, I love to hear it.

  • HTML5 video element non-seekable when using Django development server

    - by Ory Band
    Hey everyone. I've got a Django app serving a webpage with an HTML5 element. There's a wierd "feature", turning the video element to be non-seekable: video.seekable returns a timeRanges object with length=0, whereas it should be length=1. This means I can't edit the video. JavaScript can't do anything either. The thing is, when I upload the problematic webpage, statically - no Django, just plain HTML/JS/CSS - to my website for testing, it works fine - length=1. However, if I try to serve the same static page on my Django dev server still gives the same problem. I am using Django's static serving for dev/debug purposes - Do you have any idea what is causing this, or how can I fix it? Thanks.

  • Pickled my dictionary from ZODB but i got a less in size one?

    - by Someone Someoneelse
    I use ZODB and i want to copy my 'database_1.fs' file to another 'database_2.fs', so I opened the root dictionary of that 'database_1.fs' and I (pickle.dump) it in a text file. Then I (pickle.load) it in a dictionary-variable, in the end I update the root dictionary of the other 'database_2.fs' with the dictionary-variable. It works, but I wonder why the size of the 'database_1.fs' not equal to the size of the other 'database_2.fs'. They are still copies of each other. def openstorage(store): #opens the database data={} data['file']=filestorage data['db']=DB(data['file']) data['conn']=data['db'].open() data['root']=data['conn'].root() return data def getroot(dicty): return dicty['root'] def closestorage(dicty): #close the database after Saving transaction.commit() dicty['file'].close() dicty['db'].close() dicty['conn'].close() transaction.get().abort() then that's what i do:- import pickle loc1='G:\\database_1.fs' op1=openstorage(loc1) root1=getroot(op1) loc2='G:database_2.fs' op2=openstorage(loc2) root2=getroot(op2) >>> len(root1) 215 >>> len(root2) 0 pickle.dump( root1, open( "save.txt", "wb" )) item=pickle.load( open( "save.txt", "rb" ) ) #now item is a dictionary root2.update(item) closestorage(op1) closestorage(op2) #after I open both of the databases #I get the same keys in both databases #But `database_2.fs` is smaller that `database_2.fs` in size I mean. >>> len(root2)==len(root1)==215 #they have the same keys True Note: (1) there are persistent dictionaries and lists in the original database_1.fs (2) both of them have the same length and the same indexes.
