  • Get data from html form to ruby in Ruby on Rails

    - by Maestro1024
    Get data from html form to ruby in Ruby on Rails I have some html like this <html> <h1>Text to PDF</h1> <textarea name="comments" cols="40" rows="5"> Enter your Text here... </textarea><br> <input type="submit" value="Submit" /> </form> </body> </html> I want to give the value of the text into the controller for this page/view. How do I do this with rails? I am new to rails, what is the mechanism for this? I don't need to write to the database just want to hand it to the controller. If there is a good tutorial for this sort of thing that would be great, I am not convince I am approaching this correctly.

  • iPhone SDK - How is data shared in a unversal app

    - by norskben
    Stack overflow I want to make a universal version of my app available, but I am wondering how is data managed between the iPad and the iPhone versions? -Are they completely independent? or if I have a plist in the iPad app, does it also appear in the iPhone app. If so, is there any syncing etc etc. I have a few months experience with single iPad or iPhone apps, but never a universal. Thanks again.

  • Adding Insert Row in tableView

    - by user333624
    Hello everyone, I have a tableView that loads its data directly from a Core Data table with a NSFetchedResultsController. I'm not using an intermediate NSMutableArray to store the objects from the fetch results; I basically implemented inside my UITableViewController the protocol method numberOfRowsInSection and it returns the numberOfObjects inside a NSFetchedResultsSectionInfo. id <NSFetchedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex:section]; and then I configure the cell content by implementing configureCell:atIndexPath and retrieving object info from the fetchedResultController but right now I have a generic configuration for any object (to avoid complications) cell.textLabel.text = @"categoria"; I also have a NavigationBar with a custom edit button at the right that loads my own selector called customSetEditing. What I'm trying to accomplish is to load an "Insert Cell" at the beginning of the tableView so when I tap it, it creates a new record. This last part is easy to implement the problem is that I dont's seem to be able to load the insert row or any row when I tap on the navigation bar edit button. this is the code for my customSetEditing: - (void) customSetEditing { [super setEditing:YES animated:YES]; [self.tableView setEditing:YES animated:YES]; [[self tableView] beginUpdates]; //[[self tableView] beginUpdates]; UIBarButtonItem *customDoneButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(customDone)]; [self.navigationItem.rightBarButtonItem release]; self.navigationItem.rightBarButtonItem = customDoneButtonItem; //[categoriasArray insertObject:[NSNull null] atIndex:0]; NSMutableArray *indexPaths = [[NSMutableArray alloc] initWithObjects:[NSIndexPath indexPathForRow:0 inSection:0],nil ]; [self.tableView insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationTop]; //[indexPaths release]; [self.tableView reloadData];} Before adding the:[self.tableView reloadData]; I was getting an out of bounds error plus a program crash and although the program is not crashing it is not loading anything. I have seen many examples of similar situations in stackoverflow (by the way is an excellent forum with very helpful and nice people) none of the examples seems to work for me. Any ideas?

  • Displaying Data on the Form with C#

    - by The.Anti.9
    I'm searching files and returning lines that include the search text, and I'm not really sure the best way to display the information I get. Every time I get a match, I want to show, in some sort of control, the File it came from, and the whole text line. (aka streamreader.ReadLine() result). First I tried just putting it all in a read-only text box, but it doesn't have a scroll bar. What is the best form control to help me display this data neatly?

  • [Reloaded] Error while sorting filtered data from a GridView

    - by Bogdan M
    Hello guys, I have an error I cannot solve, on a ASP.NET website. One of its pages - Countries.aspx, has the following controls: a CheckBox called "CheckBoxNAME": < asp:CheckBox ID="CheckBoxNAME" runat="server" Text="Name" /> a TextBox called "TextBoxName": < asp:TextBox ID="TextBoxNAME" runat="server" Width="100%" Wrap="False"> < /asp:TextBox> a SQLDataSource called "SqlDataSourceCOUNTRIES", that selects all records from a Table with 3 columns - ID (Number, PK), NAME (Varchar2(1000)), and POPULATION (Number) called COUNTRIES < asp:SqlDataSource ID="SqlDataSourceCOUNTRIES" runat="server" ConnectionString="< %$ ConnectionStrings:myDB %> " ProviderName="< %$ ConnectionStrings:myDB.ProviderName %> " SelectCommand="SELECT COUNTRIES.ID, COUNTRIES.NAME, COUNTRIES.POPULATION FROM COUNTRIES ORDER BY COUNTRIES.NAME, COUNTRIES.ID"> < /asp:SqlDataSource> a GridView called GridViewCOUNTRIES: < asp:GridView ID="GridViewCOUNTRIES" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="SqlDataSourceCOUNTRIES" DataKeyNames="ID" DataMember="DefaultView"> < Columns> < asp:CommandField ShowSelectButton="True" /> < asp:BoundField DataField="ID" HeaderText="Id" SortExpression="ID" /> < asp:BoundField DataField="NAME" HeaderText="Name" SortExpression="NAME" /> < asp:BoundField DataField="POPULATION" HeaderText="Population" SortExpression="POPULATION" /> < /Columns> < /asp:GridView> a Button called ButtonFilter: < asp:Button ID="ButtonFilter" runat="server" Text="Filter" onclick="ButtonFilter_Click"/> This is the onclick event: protected void ButtonFilter_Click(object sender, EventArgs e) { Response.Redirect("Countries.aspx?" + (this.CheckBoxNAME.Checked ? string.Format("NAME={0}", this.TextBoxNAME.Text) : string.Empty)); } Also, this is the main onload event of the page: protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack == false) { if (Request.QueryString.Count != 0) { Dictionary parameters = new Dictionary(); string commandTextFormat = string.Empty; if (Request.QueryString["NAME"] != null) { if (commandTextFormat != string.Empty && commandTextFormat.EndsWith("AND") == false) { commandTextFormat += "AND"; } commandTextFormat += " (UPPER(COUNTRIES.NAME) LIKE '%' || :NAME || '%') "; parameters.Add("NAME", Request.QueryString["NAME"].ToString()); } this.SqlDataSourceCOUNTRIES.SelectCommand = string.Format("SELECT COUNTRIES.ID, COUNTRIES.NAME, COUNTRIES.POPULATION FROM COUNTRIES WHERE {0} ORDER BY COUNTRIES.NAME, COUNTRIES.ID", commandTextFormat); foreach (KeyValuePair parameter in parameters) { this.SqlDataSourceCOUNTRIES.SelectParameters.Add(parameter.Key, parameter.Value.ToUpper()); } } } } Basicly, the page displays in the GridViewCOUNTRIES all the records of table COUNTRIES. The scenario is the following: - the user checks the CheckBox; - the user types a value in the TextBox (let's say "ch"); - the user presses the Button; - the page loads displaying only the records that match the filter criteria (in this case, all the countries that have names containing "Ch"); - the user clicks on the header of the column called "Name" in order to sort the data in the GridView Then, I get the following error: ORA-01036: illegal variable name/number. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.OracleClient.OracleException: ORA-01036: illegal variable name/number Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Any help is greatly appreciated, tnks.

  • Core Data fetch request with array

    - by JK
    I am trying to set a fetch request with a predicate to obtain records in the store whose identifiers attribute match an array of identifiers specified in the predicate e.g. NSString *predicateString = [NSString stringWithFormat:@"identifier IN %@", employeeIDsArray]; The employeeIDsArray contains a number of NSNumber objects that match IDs in the store. However, I get an error "Unable to parse the format string". This type of predicate works if it is used for filtering an array, but as mentioned, fails for a core data fetch. How should I set the predicate please?

  • Object to Network serialization - with an existing protocol

    - by cpf
    I'm writing a client for a server program written in C++. As is not unusual, all the networking protocol is in a format where packets can be easily memcopied into/out of a C++ structure (1 byte packet code, then different arrangements per packet type). I could do the same thing in C#, but is there an easier way, especially considering lots of the data is fixed-length char arrays that I want to play with as strings? Or should I just suck it up and convert types as needed? I've looked at using the ISerializable interface, but it doesnt look as low level as is required.

  • Entity Data Model Wizzard not creating tables in EDMX file

    - by Shawn
    I'm trying the database first approach by creating an ADO.NET Entity Data Model using the Wizard with the Adventureworks2012 DB. Testing DB connection works, and the connection string is added to the App.Config. I'm selecting all the tables except the ones marked as (dbo) AWBuildVersion, DatabaseLog, and ErrorLog. When the Wizard finishes the .edmx file is blank, and if I view the file in XML view the EntityContainer is empty. I'm using VS 2010 & .NET Framework 4.0
