ruby on rails - Question about editing by multiple Models and one controller -

-

I have three models (word, adjective, adverb) and a controller (word) that have these Models. I have to manage: 

  def = edit word = Word.find (parameter [: id]) @ adjektiv = Adjektiv .find (parameter [: id]) @adverb = Adverb.find (Parameter for example: When I see an adverb of adverb (id = 1), and in the text box in Word with Eddie = 1, So I want to edit it. I like how can I do this to see Edwardb's first record? Thanks   
 
 
 Since using STI (single table legacy), there are adjextitives and verb adjective words that look like an ideal situation, in order to obtain it, you will need a string field that will be used for your words The table has been typed. You can do it like this:  
  def word & lt; ActiveRecord :: Base and Def Adjacquiv & lt; Word and Deaf Edwards & lt; Word and   
 and then in your controller:  
  def edit = word = word.find (params [: id]) end  < / Pre>

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...

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...
