cocoa - Binding a table column containing NSPopUpButtons -

-

I have a table in which one uses a NSPopUpButtonCell I am trying as much as possible, I think That is not the way to get the way I want to properly bind everything. Here's what I'm trying to do:

I have an NSArrayController that is called 'field value' from a managed object context. It is used to populate a popup menu for each item (i.e. the list of available options). I can force it by selecting cell in IB and arranging my content / objects / values ​​by 'field value' and 'reserved' objects and 'field value'. Orgates. Name as appropriate (to get the object and visual title represented).

Then I want to bind the column in such a way that the value selected in each row comes from an array in my controller class, again made visible (and edited only) by another NASRRE controller.

So far, I have managed to set it up so that there is a list of available fields in each popup menu, and that the default value is selected in each of them, in fact, when selecting an item The effect does not, however - it has just returned to its initial value. I have also managed some other adaptations on it, like the menu has been populated with the values ​​selected, or the name and selection of all the available values, -description any value that I added No.

I'm sure I'm missing something quite simple, but I'm not sure what this is. Probably I have forgotten to tie these types of data (such as content versus content object versus content value stuff), but if I can see it now I am ashamed.

Thank you very much: o)

I have the same with table view Although the data source is not core data based, but I have seen one thing, you can double check that there may be a subtle difference in my setup for the table column, I have only the table column contents, content Created by value and selected object. However, it seems that it is possible to bind the actual NSPopUpButtonCell instead. Probably this works when binding tables are on the column, but when they are not on the actual cell? Anyway, there is one thing that can be worth seeing.

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
