CakePHP: showing fail/success message under Ajax login form -

-

I use the AUTH component. I have a login form and I want to show a success / failure message without a page refreshes.

But when I submit a form ( jquery.form.js ): 

  $ ('# login form'). Ajaxform (data) {alerts (data);});   
 It returns  home.ctp  content in case of success and returns the HTML code of the login form in case of failure!  
 I have  $ this-> AUTH- & gt; I want to get  alert (data)  in the login error .  
 These are some of the app_transfer  beforeFilter  settings:  
  before the function filter () {$ this-> AUTH- & gt; LoginRedirect = false; $ This- & gt; AUTH- & gt; Logout redirect = false; $ This- & gt; AUTH- & gt; LoginError = __ ('Invalid e-mail or password.', True); $ This- & gt; AUTH- & gt; Auto redirect = false; $ This- & gt; Autorander = False; $ This- & gt; Presenting ('Login', 'Ajax'); }   
 I used LogOnRed to render some arguments and to create an object for the jQuery process.   
 
 
 You can use the solution from blogpost  .  
 Actually, this is a request from  Ajax  to differentiate it from an  standard :  
  $ This-> Request Handler-> IsAjax ()) / / If this is an Ajax call / / and other / if this is a standard action request / /   
 and However, the debug level is set to 0 ( configure :: write ('debug', 0) ) and standard  XHTML layout  in  / app / views / layouts / default. Ctp .  Ajax layout  for output data in standard  . 
 Debug of submitted form looks like this:  
  Configure :: Write ('debug', 0); $ This- & gt; Layout = 'Ajax'; If ($ this-> Request Handler-> is Ajax ()) {If (! ($ -> Data below!) {$ This-> Post- & gt; Create (); $ This- & gt; Later & gt; Set ($ this-> data ['post']); If ($ this- & gt; Post- & gt; Valid ()) {If ($ -> this-> Post-> Save ($ -> -> Data)) {$ message = __ ( 'Post has been saved.', True); $ Data = $ this- & gt; Data; $ This- & gt; Set ('success', compact ('message', 'data')); }} And {$ message = __ ('Post could not be saved. Please try again.', True); $ Post = $ this- & gt; Post- & gt; InvalidFields (); $ Data = compact ('post'); $ This- & gt; Set ('Errors', compact ('message', 'data')); }}   
 and the subsequent output is done in JSON format:  
  // error output {"errors": {"message": " The post could not be saved, please try again. "," Data ": {" post ": {" title ":" This field can not be left blank. "," Body ":" This field is not left blank Success "{{"} ": {" Message ":" Post has been saved. "," Data ": {" Post ": {" id ":" "," Title " : "Epsom Dollar Seat AMTiet", "Body": "Laurum Indies Dollar Seat A Mate, Ellicott ... "," Published ":" 1 "}}}}

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
