sql - ruby on rails equivalent statement of find_by_sql -

-

What will happen when given the following given below? 

  @mostviews = post .find_by_sql ("select posts.id, from posts.title posts countpages.post_id = count.pages.counts desc range 5 on orders.id command" 5) @temp = Post.find_by_sql ("Selection post_id, COUNT (*) counts posts as a post_id by the group by AS count, posts = posts.find_by_sql (" select posts .post, posts title, comment_count.count inner joiner posts) comment_count.post_id = posts.id Comment on "Count 5" from the limit of DESC as count; ")   
 Is it possible that you find or use the function?   
 
 
  post. Selection ("Post id, posts.title"). Join ((countpage) .order ("countpages.counts desc"). Limit (5)   
 This count is a union Otherwise, you may be more explicit in joining ("INNER JOIN ... ")

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...
