python - Django Tutorial: Where does the other objects come from? -


i have been reading , following django tutorial https://docs.djangoproject.com/en/1.3/intro/tutorial01/ running django 1.3.1, , python 2.7.3 on xubuntu 12.04 lts virtual machine 512 mb ram if matters.

actually found exact question, reference seems out of date. have viable link reference? where 'article_set' come in django?

thank in advance.

django foreignkey lookups establish relations between related objects. these relations added dynamically accessors suffixed _set 

def get_accessor_name(self):     # method encapsulates logic decides name give     # accessor descriptor retrieves related many-to-one or     # many-to-many objects. uses lower-cased object_name + "_set",     # can overridden "related_name" option.     if self.field.rel.multiple:         # if symmetrical m2m relation on self, there no reverse accessor.         if getattr(self.field.rel, 'symmetrical', false) , self.model == self.parent_model:             return none         return self.field.rel.related_name or (self.opts.object_name.lower() + '_set')     else:         return self.field.rel.related_name or (self.opts.object_name.lower())

code in django sources (models/related.py)

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
