php - Modifying Containable fields required in beforeFind callback? -

-

In my KPPP 1.2.5 app, I have a profile model that is the user The model user model has a username field, and when I execute find () on the profile model, I always automatically User.username also

This is what I tried to do: 

 
 
  before the public event ($ queryData) {// Determine that the username is already un Locking in that return data has been 'User.username' or 'User' = & gt; Array ('username'). $ Uuserdata = release ($ querydata ['contains']) & amp; Amp; In_array ("user. {$ This-> user- & gt; displayField}", $ queryData ['contain']); $ Uuser data | = Release ($ query data ['include'] ['user']) & amp; Amp; In_array ($ this-> User-> displayField, $ queryData ['contains'] ['user']); // Request that the user's data should be included, if the calling method has not already been requested ($! UserData) {$ queryData ['contain'] ['user'] [] = $ this- & Gt; User- & gt; DisplayField; } $ QueryData; }  
 
 I can see that the value of  $ queryData ['contain']  is being updated properly, but the user name will not be retrieved Used to be. I looked at the CakePHP core code for the search ()  method, and I found that the  beforeFind ()  callback is being called after the callback of all the behaviors, which means That's what needs to be done with the already containable  $ queryData ['contain']  before I was able to modify it. 
 
 How can I work without the core?

I have solved it, so here's my answer because someone has the same complexity. The containable fields can not be specified in the first, before all the biologists' () methods before before the model beforeFind () Method is called. >

In this way, to add to my custom containable field, it was necessary to modify the find () method directly on my profile model. 

  public work ($ terms = zero, $ field = array), $ order = zero, $ recursive = zero) {$ this-> ("{$ This-> user- & gt; nickname}. {$ This-> user- & gt; displayField}"); Return Parent :: Find ($ terms, $ fields, $ order, $ recursive); }

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...
