  • NSPredicate acting strange in NSFetchedResultsController

    - by Scott Langendyk
    I feel as if this should be very simple, but it's behaving strangely. I have 3 entities, with a relationship as such Entity A <-- Entity B <<-- Entity C I have an NSFetchedResults controller and I'm trying to filter the results of Entity A using the following predicate. [NSPredicate predicateWithFormat:@"NONE entityB.entityC == %@", self.entityC]; When I try and run the app, the output shows no results. I can alter the predicate slightly to: [NSPredicate predicateWithFormat:@"ANY entityB.entityC == %@", self.entityC]; And it shows me only the results that I want it to filter out. Why is this happening?

  • Rails transaction: save data in multiple models.

    - by smotchkkiss
    my models class Auction belongs_to :item belongs_to :user, :foreign_key => :current_winner_id has_many :auction_bids end class User has_many :auction_bids end class AuctionBid belongs_to :user end current usage An item is displayed on the page, the user enters an amount and clicks bid. Controller code might look something like this: class MyController def bid @ab = AuctionBid.new(params[:auction_bid]) @ab.user = current_user if @ab.save render :json => {:response => 'YAY!'} else render :json => {:response => 'FAIL!'} end end end desired functionality This works great so far! However, I need to ensure a couple other things happen. @ab.auction.bid_count needs to be incremented by one. @ab.user.bid_count needs to be incremented by one @ab.auction.current_winner_id needs to be set to @ab.user_id That is, the User and the Auction associated with the AuctionBid need values updated as well in order for the AuctionBid#save to return true.

  • Efficient algorithm to find first available name

    - by Avrahamshuk
    I have an array containing names of items. I want to give the user the option to create items without specifying their name, so my program will have to supply a unique default name, like "Item 1". The challenge is that the name has to be unique so i have to check all the array for that default name, and if there is an item with the same name i have to change the name to be "Item 2" and so on until i find an available name. The obvious solution will be something like that: String name; for (int i = 0 , name = "Item " + i ; !isAvailable(name) ; i++); My problem with that algorithm is that it runs at O(N^2). I wonder if there is a known (or new) more efficient algorithm to solve this case. In other words my question is this: Is there any algorithm that finds the first greater-than-zero number that dose NOT exist in a given array, and runs at less that N^2? Thanks!

  • How to prevent column b containing the same value as any column a in Oracle?

    - by Janek Bogucki
    What is a good way to prevent a table with 2 columns, a and b, from having any record where column b is equal to any value in column a? This would be used for a table of corrections like this, MR -> Mr Prf. -> Prof. MRs -> Mrs I can see how it could be done with a trigger and a subquery assuming no concurrent activity but a more declarative approach would be preferable. This is an example of what should be prevented, Wing Commdr. -> Wing Cdr. Wing Cdr. -> Wing Commander Ideally the solution would work with concurrent inserts and updates.

  • Inserting Large volume of data in SQL Server 2005

    - by Manjoor
    We have a application (written in c#) to store live stock market price in the database (SQL Server 2005). It insert about 1 Million record in a single day. Now we are adding some more segment of market into it and the no of records would be double (2 Millions/day). Currently the average record insertion per second is about 50, maximum is 450 and minimum is 0. To check certain conditions i have used service broker (asynchronous trigger) on my price table. It is running fine at this time(about 35% CPU utilization). Now i am planning to create a in memory dataset of current stock price. we would like to do some simple calculations. I want to know different views of members on this. Please provide your way of dealing with such situation.

  • How does a hash table work?

    - by Arec Barrwin
    I'm looking for an explanation of how a hashtable works - in plain English for a simpleton like me! For example I know it takes the key, calculates the hash (how?) and then performs some kind of modulo to work out where it lies in the array that the value is stored, but that's where my knowledge stops. Could anyone clarify the process. Edit: I'm not looking specifically about how hashcodes are calculated, but a general overview of how a hashtable works.

  • Need a mysql query to extract data from mm-forms

    - by Kirill
    http://cl.ly/201a11b430bf60ef9e97 is what the rows look like, after I clean them up a bit: SELECT fk_form_joiner_id,form_key,value FROM wp_contactform_submit_data WHERE form_key!='page_post_id' AND form_key!='captcha-802' AND form_key!='page_post_title' AND form_key!='user_ID' What I need is a query where it would transform this into a structure like: id | First-name | Surname-name | your-email | dob | address-1 | address-2 | county | postcode | phone ------------------------------------------------------------------------------------------------------- 88 | jack | Somethin | [email protected] | dob | (etc) I think I know a way to do this through php, but I think there must be a way to do it as a mysql query. Ultimately, I need to export this (into a csv), but if you could give me a query that would output this into a mysql table (or at least a workable select query, that I could then turn into an insert query loop, to create a table), I'd do it form there. Thank you.

  • PHP Doctrine: Custom nested set?

    - by ropstah
    Is it possible to have nested set capabilities in this somewhat custom setup? Consider these 4 tables: Object: (oid, name) contains: [1, 'Licence'] and [2, 'Exemption'] Licence: (lid, name) Exemption: (eid, name) Cost: (oid, oid_ref, cost_oid, cost_oid_ref) For: P = Licence with lid [1] R = Exemption with eid [2] i can say "object P is a parent to object R" if the following Cost record exists: [oid: 2 oid_ref: 2 cost_oid: 1 cost_oid_ref: 1] I understand that this creates somesort of 'conditional foreign key' relation which I need to define in code. Is it possible to have the nested set loaded with these conditions?

  • Access data returned from server

    I am looking to access the actual value returned from the server.getRowData returns the value after unformat applied to the value. This results in loss of information. For instance, if a double value is rounded to two decimal places and if I want to populate the form for edit with the original value returned from the server with 6 decimals, how can I get the value returned. for eg: Value returned from server : 12.345678 formatter option for column : formatter: 'number', formatoptions: {thousandsSeparator: ",", decimalPlaces: 2} Value displayed in grid : 12.35 How do I retrieve the value 12.345678 returned from the server. getRowData returns 12.35

  • What are the reasons to store documents into DBMS when using Alfresco DMS

    - by Julia
    Hello guys! I have interview for an internship with company that wants to implement document management system and they are considering on the first place open source solutions, their top choice being Alfresco, but decision is still not final, part of my work there would be to investigate is Alfresco the best solution. What I have seen from project description, is that they would implement Alfresco with MySQL database, and not to use DBMS just for document metadata and indexing, but they actually want to store documents inside. By company profile, type of documents would be mostly PDF and .doc, not images. I have researched a bit, and I have read all the topics here related to storing files into the database, not to duplicate a question. So from what I understand, storing BLOBS is generally not recomendable, and by the profile of the company and their legal obligations with archiving, I see they will have to store larger amount of docs. I would like to be ready as much as I can for the interview and that is why I would like your opinion on these questions: 1) What will be your reasons for deciding to store documents into the DBMS, (especially having in mind that you are installing Alfresco, which stores files in the FS)??? 2) Do you have any experiences with storing documents into the MySQL database specifically??? All the help is very much appreciated, I am really excited about interview and really want this internship, so this is one of things i really want to understand before!! Thank you!!!!

  • iphone, get the object count without performing a fetch?

    - by Andrew
    Hi, I seem to recall that it's possible to return the resulting object count from an NSPredicate in CoreData without actually performing a fetch, but I can't find any reference to this. Can someone confirm that I wasn't dreaming (sad dream to have!), and would this be safe to do in another thread? Thanks Andy

  • Filling data in FormView from different tables

    - by wacky_coder
    Hi, I am using a FormView in an online quiz page for displaying the questions and RadioButtons (for answers) http://stackoverflow.com/questions/2438219/online-quiz-using-asp-dot-net Now, I need to pick the questions according to a TestID and a particular Set of that Test. The testid and the set_number would be passed using Session variables. I'm having 3 testIDs and 3 Sets per TestID and, thus, am using 9 tables to store the Questions, the Options and the correct answer. I need help on how to set the FormView so that it extracts the questions from a particular table only. Do I need to use a StoredProcedure ? If yes, how? PS: If I use only one table to store all the questions from each Set and for each TestID, I can do that, but I'd prefer using separate tables.

  • UICollectionView with one static cell and N dynamic ones from a fetchresultscontroller exception

    - by nflacco
    I'm trying to make a UITableView that shows a blog post and comments for that post. My setup is a tableview in storyboard with two dynamic prototype cells. The first cell is for the post and should never change. The second cell represents the 0 to N comments. My cellForRowAtIndexPath method shows the post cell properly, but fails to get the comment at the given index path (though if I comment out the fetch I get the appropriate number of comment cells with a green background that I set as a visual debug thing). let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment I get the following exception on this line: 2014-08-24 15:06:40.712 MessagePosting[21767:3266409] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]' *** First throw call stack: ( 0 CoreFoundation 0x0000000101aa43e5 __exceptionPreprocess + 165 1 libobjc.A.dylib 0x00000001037f9967 objc_exception_throw + 45 2 CoreFoundation 0x000000010198f4c3 -[__NSArrayM objectAtIndex:] + 227 3 CoreData 0x00000001016e4792 -[NSFetchedResultsController objectAtIndexPath:] + 162 Section and cell setup: override func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int { // #warning Incomplete method implementation. // Return the number of rows in the section. switch section { case 0: return 1 default: if let realPost:Post = post { return fetchedResultController.sections[0].numberOfObjects } else { return 0 } } } override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { switch indexPath.section { case 0: let cell = tableView.dequeueReusableCellWithIdentifier(postViewCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = lightGrey if let realPost:Post = self.post { cell.textLabel.text = realPost.text } return cell default: let cell = tableView.dequeueReusableCellWithIdentifier(commentCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = UIColor.greenColor() let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment // <---------------------------- :( cell.textLabel.text = comment.text return cell } } FRC: func controllerDidChangeContent(controller: NSFetchedResultsController!) { tableView.reloadData() } func getFetchedResultController() -> NSFetchedResultsController { fetchedResultController = NSFetchedResultsController(fetchRequest: taskFetchRequest(), managedObjectContext: managedObjectContext, sectionNameKeyPath: nil, cacheName: nil) return fetchedResultController } func taskFetchRequest() -> NSFetchRequest { if let realPost:Post = self.post { let fetchRequest = NSFetchRequest(entityName: "Comment") let sortDescriptor = NSSortDescriptor(key: "date", ascending: false) fetchRequest.predicate = NSPredicate(format: "post = %@", realPost) fetchRequest.sortDescriptors = [sortDescriptor] return fetchRequest } else { return NSFetchRequest(entityName: "") } }

  • find(:all) and then add data from another table to the object

    - by Koning Baard XIV
    I have two tables: create_table "friendships", :force => true do |t| t.integer "user1_id" t.integer "user2_id" t.boolean "hasaccepted" t.datetime "created_at" t.datetime "updated_at" end and create_table "users", :force => true do |t| t.string "email" t.string "password" t.string "phone" t.boolean "gender" t.datetime "created_at" t.datetime "updated_at" t.string "firstname" t.string "lastname" t.date "birthday" end I need to show the user a list of Friendrequests, so I use this method in my controller: def getfriendrequests respond_to do |format| case params[:id] when "to_me" @friendrequests = Friendship.find(:all, :conditions => { :user2_id => session[:user], :hasaccepted => false }) when "from_me" @friendrequests = Friendship.find(:all, :conditions => { :user1_id => session[:user], :hasaccepted => false }) end format.xml { render :xml => @friendrequests } format.json { render :json => @friendrequests } end end I do nearly everything using AJAX, so to fetch the First and Last name of the user with UID user2_id (the to_me param comes later, don't worry right now), I need a for loop which make multiple AJAX calls. This sucks and costs much bandwidth. So I'd rather like that getfriendrequests also returns the First and Last name of the corresponding users, so, e.g. the JSON response would not be: [ { "friendship": { "created_at": "2010-02-19T13:51:31Z", "user1_id": 2, "updated_at": "2010-02-19T13:51:31Z", "hasaccepted": false, "id": 11, "user2_id": 3 } }, { "friendship": { "created_at": "2010-02-19T16:31:23Z", "user1_id": 2, "updated_at": "2010-02-19T16:31:23Z", "hasaccepted": false, "id": 12, "user2_id": 4 } } ] but rather: [ { "friendship": { "created_at": "2010-02-19T13:51:31Z", "user1_id": 2, "updated_at": "2010-02-19T13:51:31Z", "hasaccepted": false, "id": 11, "user2_id": 3, "firstname": "Jon", "lastname": "Skeet" } }, { "friendship": { "created_at": "2010-02-19T16:31:23Z", "user1_id": 2, "updated_at": "2010-02-19T16:31:23Z", "hasaccepted": false, "id": 12, "user2_id": 4, "firstname": "Mark", "lastname": "Gravell" } } ] I thought of a for loop in the getfriendrequests method, but I don't know how to implement this, and maybe there is an easier way. It must also work for XML. Can anyone help me? Thanks

  • Avoid the collapsing effect on TreeView after updating data

    - by Manolete
    I have a TreeView used to display events. It works great, however every time new events are coming in and populating the tree collapse the tree again to the original position. That is very annoying when the refresh time is less than 1 second and it does not allow the user to interact with the items of the tree. Is there any way to avoid this behaviour? <TreeView Margin="1" BorderThickness="0" Name="eventsTree" ItemsSource="{Binding EventAlertContainers}" Background="#00000000" ScrollViewer.VerticalScrollBarVisibility="Auto" FontSize="14" VirtualizingStackPanel.IsVirtualizing="True"> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type C:EventAlertContainer}" ItemsSource="{Binding EventAlerts}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="3,0" Source="Resources\Process_info_32.png" /> <TextBlock FontWeight="Bold" FontSize="16" Text="{Binding Description}" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type C:EventAlert}" ItemsSource="{Binding Events}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="0,0" Source="Resources\clock2_32.jpg" /> <TextBlock FontWeight="DemiBold" FontSize="14" Text="{Binding Name}" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type C:Event}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="0,0" Source="Resources\Task_32.png" /> <StackPanel Orientation="Vertical"> <TextBlock FontSize="12" Text="{Binding Name}" /> </StackPanel> </StackPanel> </HierarchicalDataTemplate> </TreeView.Resources> </TreeView>
