records

How shall I set the form fields to be able to insert multiple rows in the database for a single model. I am updating a div with another link and cannot use the form helper. So I need to set the field names manually. I have a post model and it has a title field. I want to insert i posts to db like post[0][title] But when I name the form field like this It gets 0 as string and does not record. Also I tried to set the Array my self from Rails Console like post = Array.new post << [:title => "title 1"] post << [:title => "title 2"] sav = Post.new(post) sav.save And still nothing is saved. posts =

I'M GOING TO ASK THIS FOR THE SECOND TIME. I'M GOING TO MAKE IT CLEAR SO YOU CAN HELP ME :) Okay let's start. I have a Registration Process. I split the process into two page. The first page is for "Personal Information" only. Then when i click the next button the next page will appear (postbackURL) This page is for "Upload Photo" page. They work fine! the data and the image are displayed on my gridview control. But my problem is here: As you can see in the figure below. The data are populated in two rows! I want them to appear in only single row! I think the problem is THE DATABASE FROM PAGE

I have a record: (defrecord Point [x y]) (def p (Point. 1 2)) Now I want to extract just the map from the record. These ways get the job done. Are these good ways? Are there better ways? (into {} (concat p)) (into {} (map identity p)) (apply hash-map (apply concat p)) I was hoping there might be a cleaner way, perhaps built-in to the notion of a record. Records are maps (defrecord Thing [a b]) (def t1 (Thing. 1 2)) (instance? clojure.lang.IPersistentMap t1) ;=> true So, in general there is no need to coerce them into a APersistentMap type. But, if desired you do so with into : (into {} t1) ;=>

I need to delete all the duplicated records from one of my tables the problem is that there isn't any id or unique or key column so I can't make something like this: delete from tbl using tbl,tbl t2 where tbl.locationID=t2.locationID and tbl.linkID=t2.linkID and tbl.ID>t2.ID because it needs an id column or unique or key column and I can't make an ALTER IGNORE TABLE 'mytable' ADD UNIQUE INDEX because there is information that will be always necessary duplicated but others don't and I can't make this: DELETE FROM 'table' WHERE 'field' IN (SELECT 'field' FROM 'table' GROUP BY 'field'HAVING

In Delphi 7, you a record was nothing more than a collection of data grouped into one location. In the last few versions, you've been able to add public and private members, methods, properties and constructors to them, treating them a lot more like objects. What version was this extended syntax introduced in? EDIT: In case anyone wonders why I'm asking, I'm trying to set up something that would be simplified quite a bit by using the extended syntax, but I want to make it backwards-compatible with older versions of Delphi, so I need to know which IFDEFs to use. I'm pretty sure records with

I'm writing a modular and extensible text editor in Haskell and I'd like to implement plugins in such a way: The writer of the plugin provides a single function that looks something like this: handleEvent :: (PluginState, EditorState) -> Event -> (PluginState, EditorState) As each event occurs the plugin can use the current editor state and customized chunk of its own state to calculate a new editor state and new plugin state. Of course each Plugin is going to have a different Type for the Plugin state, so I'm getting stuck on how I can integrate this into my system in a general way. How can I

I want to insert only Distinct Records from Table "A" to Table "B". Assume both the tables has same structure. TheJubilex INSERT INTO B SELECT DISTINCT * FROM A You might not want the id column of the table to be part of the distinct check, so use this solution if that's the case: https://stackoverflow.com/a/5171345/453673 If by DISTINCT you mean unique records that are on TableB that aren't already in TableA, then do the following: INSERT INTO TableB(Col1, Col2, Col3, ... , Coln) SELECT DISTINCT A.Col1, A.Col2, A.Col3, ... , A.Coln FROM TableA A LEFT JOIN TableB B ON A.KeyOfTableA = B
