[google-appengine] Pagination
HI,
I somehow have the feeling that for pagination, cursors,
memcache and task queues can be used. But I can't get my head around
to get the exact code. Any experts here who can help?
The idea is like this ..
First time the query runs do something like this
q=Something.all()
q.filter
and so on ...
total_results=q.count()
q.limit(20) # say,
current_results=q.count() # what if it only returned 15 at the end ?
self.response.out.write(" Showing " + str(current_results) + " of "
+str(total_results))
Add a task with current query as parameter(somehow, may be get some
kind of unique id for it or something) . The task should generate all
(or a set of next N*5) cursors ready in a memcached list(may be comma
seperated row)
The next time the cgi runs it should first check if there is a
memcached list of cursors for the current and next (and may be
previous) N set of pages .. if not , call the task again to generate
it. If it was existing , use the cursors from the memcached list.
the task could do something like this :
q=soemthing.all()
if cursor:
q.with_cursor(cursor)
q.limit(20)
next_cursor=q.cursor()
add the cursor to cache with unique session/query id
rinse, repeat till satisfied.
what say?
I know there are a bunch of errors in the code above .. Its just to
give an idea.
if cursor:
q.with_cursor(cursor)

I was thinking about using memcache for paging (of articles) too, I did not think about using cursors though, as I have only very shallow experience with them.

[google-appengine] datastore design for hierarchical data.
hi , i am designing a simple project based to do list. the idea is to define tasks under project ( no workflow - just "task is completed" or not is required. ) in a hirarchial way. i.e. each task has multiple task and that task may have other multiple task. a project can be said to be completed if all task under that project are completed. , i tought of using refrenceproeperty to create hirarchy , but could not figure out easy way ( which do not take more than 30 seconds to find all the children of a project and check weather it is completed or not ) . to detect if project is complete or not. how to design database for such job ? and also , if i need to copy the project in order to define another project , how to copy hierarchical data ? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

one idea is to store both , reference value of project as well as reference value of parent task in a child task.

Re: [google-appengine] datastore design for hierarchical data.
How about updating all ancestors on task status change? That way you wouldn't need to find all the children.

[google-appengine] Re: datastore design for hierarchical data.
Here is the approach I would probably take unless you have many hundreds of child tasks. I would keep a list of keys of all children of each project/task. (You can then do a db.get and get all immediate children with single call) and each child has a reference to it's parent. In addition in each item keep a list of all parents keys back to the root. That way you can search for all children in part of the tree/subtree (This approach is especially useful if you have multiple child types) as back ref sets are kind specific. Keep a running count of complete children at each level, rather than trying to calculate the current state in a single big function, (keep these subsidiary values up to date through tasks) T On Apr 18, 8:29 pm, gops wrote: > hi , i am designing a simple project based to do list. the idea is to > define tasks under project ( no workflow - just "task is completed" or > not is required. ) in a hirarchial way. i.e. each task has multiple > task and that task may have other multiple task. a project can be said > to be completed if all task under that project are completed. , i > tought of using refrenceproeperty to create hirarchy , but could not > figure out easy way ( which do not take more than 30 seconds to find > all the children of a project and check weather it is completed or > not ) . to detect if project is complete or not. how to design > database for such job ? and also , if i need to copy the project in > order to define another project , how to copy hierarchical data ? > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine" group. > To post to this group, send email to google-appeng...@googlegroups.com. > To unsubscribe from this group, send email to > google-appengine+unsubscr...@googlegroups.com. > For more options, visit this group > athttp://groups.google.com/group/google-appengine?hl=en. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Google Data API to talk to App Engine Service
Two diff ways can be used. 1. Google Account auth. There is a simple example somewhere on the tutorial on this. Should be easy. 2. Another way (which I am using as not all my users have google account), is to create local User account and hash of a password. Only client knows the password. Then create a session when user auths. Send session id back and cache it. You can do a lot of fancy security stuff with that (out of the scope of this reply). Then every call needs to have session id. I would also include a some integrity check by HMACing the payload etc. Also, one can use a clever JSESSION cookie usage if on the browser. -mandar On Apr 17, 6:26 pm, formtester wrote: > Still couldn't figure out how to authenticate myself with App Engine > service, and get data from it. > Anyone ever did this before? > > On Apr 15, 12:48 am, formtester wrote: > > > Hi, > > > I'm looking for a Google API that will let me talk to App Engine > > Service, and get user's information regarding their App Engine > > service.

[google-appengine] Macro question about getting video conference functionality in a custom Web App
Hi all, I'm working with a few friends to design a desktop client that will have Skype-like functionality (think Chat roulette). We are planning on leveraging the App Engine to build it since we are so much more familiar with web programming anyway, then we're going to package it as a desktop client using Adobe Air. In general, I am trying to get a sense for the easiest and fastest ways to build XMPP chat and video functionality into an App Engine app. I would really appreciate any ideas you guys might be able to throw our way. I've looked at libjingle (Google's videoconfereincing code), but am worried about how hard it will be to plug it into the App engine considering the fact that libjingle is C++. Is there some other kind of plug-in or add-on that would give us the ability to set up video conferences in a web app? Thanks very much for your help!

[google-appengine] Re: Google Data API to talk to App Engine Service
Sorry, I guess I was referring to the wrong things. Instead of authentication, I actually wanted to do authorization, so that I can access the data the user have stored in Google applications. In my case, I wanted to access their App Engine data (such as the application IDs that they have, etc2).

Yes, but that means fixing things on the client side. For each admin, this needs to be configured. There's gotta be a way to do this on the appengine side...

[google-appengine] Re: taskqueue.add Invalid arguments: queue_name
I can answer my own question on this one. The docs are a little confusing it seems to me. They seem to suggest that one can pass queue as a kw to taskqueue.add. What you have to do if you want to do this ... apparently ... is create an instance of Task and THEN use task.add (queue_name='foo').

Hi Nick, I had to revert the change (a new feature that increased requests) because users were getting "Over quota error" once a while (1 of 6 tries more or less). That was Thursday.

[google-appengine] Limiting Cron jobs by time of day
Is there a syntax for cron jobs that limits when they run? For example, can I specify that a cron job run every every hour between 9am and 9pm? schedule: every 1 hour [except 10pm-8am] Is there a different, verbose syntax that lists every time it runs rather than using some kind of exception clause? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Limiting Cron jobs by time of day
off the top of my head.. you could define a cron job for every hour 9am, 10am, 11am, 12am with different names like job-9, job-10, job-11 but have them all point to the same url to initiate the cron job.

I have to look at them, this sounds promising. > See, with cursors, you can do basic pagination of entries (not the content of the entries themselves. Like if you have 200 entries in the datastore for an entity type, you can show 10 at a time and using the cursor, you can generate a "next" link. But that in turn poses a problem: you can only generate a "next" link, and not "previous" link. So my idea for the solution is to go over the remaining results in a quick way, and cache the cursors that point to first page, second page and so on.. in a csv in memcache entry(session managed, of course). Now using this memcache entry, you can generate a whole array of page links. The next problem that arises is that if the database has grown too big, then the csv generation will be slow(as it has to jump a lot of times). So the next idea is , instead of generating all cursors in the main cgi , the main cgi generates only first few set of page links, and then triggers a task queue entry to continue from there. By the time the user would have read the first page and clicks on "next page", the task would have generated few more entries. As the set of cursors for pagination is in memcache, you can use it even in your first page, if you are using AJAX (guessing, not that sure.) -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
