ruby on rails - Problem while editing a record -

-

I had to edit a record of my table in Rail Priya 3 but this error happened: ActiveRecord :: RecordNotFound Word Controller # Edit In My Controller: 

  Edit Defy adverb = adverb.find (: id) end   
 And in my opinion I have:  
  & lt;% @ adverb.each do | Av | & Gt%; & Lt; Tr class = "& lt;% = cycle (" weird "," even ") -%>" & Gt; & Lt; Td> & Lt;% = av.name% & gt; & Lt; / Td> & Lt; Td> & Lt;% = av.bedeutung% & gt; & Lt; / Td> & Lt; TD & gt; & Lt;% = link_to 'edit', {: controller = & gt; 'Word',: action => 'Edit' ,: ID = & gt; Av.id}%> & Lt; / TD & gt; & Lt; / TR & gt; & Lt;% end% & gt;   
 How can I solve this problem?   
 
 
 Try    @adverb = Adverb.find (params [ : Id])

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...

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...
