  • How to combine Translate and Soft Deletable Behavior in CakePHP 1.2.7?

    - by m99
    Hi guys, i'm trying to combine Translate Behavior and Mariano Iglesias' Soft Deletable Behavior Revision 49. But always if a want to soft delete a record which hasMany other records, which are translated (located in the i18n-table partly), the related hasMany records aren't soft deleted. Example: Post hasMany Comments (dependent = true) Post actsAs SoftDeletable Comments actsAs SoftDeletable, Translate Post record get's soft deleted, but I also get an error for the dependent Comment records and they aren't soft deleted. Any suggestions? Thanks in advance Marco

  • how to specify a BIGINT in a ruby scaffold?

    - by webdestroya
    I am trying to create a model in ruby that uses a BIGINT datatype (as opposed to the INT done by :integer). I have search all over Google, but all I seem to find is "run an SQL statement to alter the table to a BIGINT" - This seems a bit hack-ish to me, so I wanted to know if there was a way to specify a bigint in the ruby system like :big_int or something Any ideas?

  • SQL inserting value of a specific column under multple case

    - by Lo Wai Lun
    Suppose I have got a table which I have to insert the description of the contract under different keys of contract. But when executing, there is a n error near then Is there any limitation of using syntax set ? The below is my SQL declare @i int, @j v nvarchar(MAX) set @i = 1 while (@i<=8) begin set @j = case when @i = 1 then 'CR' when @i = 2 then 'Facebook' else 'N/A' end INSERT INTO CostNature (CNKey, CNNDescription) VALUES (@i , @j ); set @i = @i + 1 end

  • ASP.NET Compiled vs Uncompiled DB qualifiers

    - by rlb.usa
    We have an ASP.NET application that uses SQL statements, where table names are unqualified. When compiled, it works fine, but when uncompiled, it complains and errors out, saying these tables dont' exist. (Qualified name looks like Select * from MyDatabase.mySchema.MyTable ; Unqualified like Select * from MyTable) If you try these queries on the database, by yourself, it will take only the qualified names. What's going on? I thought Compiled vs Uncompiled apps should perform the same way codewise.

  • Cepstral Analysis for pitch detection

    - by Ohmu
    Hi! I'm looking to extract pitches from a sound signal. Someone on IRC just explain to me how taking a double FFT achieves this. Specifically: take FFT take log of square of absolute value (can be done with lookup table) take another FFT take absolute value I am attempting this using vDSP I can't understand how I didn't come across this technique earlier. I did a lot of hunting and asking questions; several weeks worth. More to the point, I can't understand why I didn't think of it. I am attempting to achieve this with vDSP library. it looks as though it has functions to handle all of these tasks. However, I'm wondering about the accuracy of the final result. I have previously used a technique which scours the frequency bins of a single FFT for local maxima. when it encounters one, it uses a cunning technique (the change in phase since the last FFT) to more accurately place the actual peak within the bin. I am worried that this precision will be lost with this technique I'm presenting here. I guess the technique could be used after the second FFT to get the fundamental accurately. But it kind of looks like the information is lost in step 2. as this is a potentially tricky process, could someone with some experience just look over what I'm doing and check it for sanity? also, I've heard there is an alternative technique involving fitting a quadratic over neighbouring bins. Is this of comparable accuracy? if so, I would favour it, as it doesn't involve remembering bin phases. so questions: does this approach makes sense? Can it be improved? I'm a bit worried about And the log square component; there seems to be a vDSP function to do exactly that: vDSP_vdbcon however, there is no indication it precalculates a log-table -- I assume it doesn't, as the FFT function requires an explicit pre-calculation function to be called and passed into it. and this function doesn't. Is there some danger of harmonics being picked up? is there any cunning way of making vDSP pull out the maxima, biggest first? Can anyone point me towards some research or literature on this technique? the main question: is it accurate enough? Can the accuracy be improved? I have just been told by an expert that the accuracy IS INDEED not sufficient. Is this the end of the line? Pi PS I get SO annoyed (npi) when I want to create tags, but cannot. :| I have suggested to the maintainers that SO keep track of attempted tags, but I'm sure I was ignored. we need tags for vDSP, accelerate framework, cepstral analysis

  • How to add additional data column in EF using ASP.Net MVC 2

    - by Picflight
    My Table: [LocationId] [Address] [ZipCode] When I show a list of Location's, I also want to show the distance from a given zip code. In Asp.Net Web Forms I had a stored procedure that would return the distance and I would call this SP on ItemDataBound on my GridView. Or, I also would have my SP that is returning the Location list add another column ([Distance]) which I could display in my GridView. How would you do this using Entity Framework and Asp.Net Mvc 2?

    I am using Entity Framework now and using a stored procedure to populate my entity. Where there is no problem with populating my entity, but when i trying to bind the result to a gridview control with "Enable Paging" set to true, it gives an error saying "The data source does not support server-side data paging." I am using stored procedure because one of the table column is FullTextIndexed, and there is a requirement to be able to search on that field. Can anyone tell me how the paging would work in this situation?

  • *Right* outer join in LINQ

    - by Rap
    Is it safe to say that there is no such thing as a right outer join in LINQ? I know to effectively create one, you'd just swap the tables in a left outer join. But can you apply the DefaultIfEmpty() method to the table on the left side of the equijoin to make it a right outer join?

    Hi Why does XHTML 1.0 Strict display a line height as appearing larger than a line height of the same value in XHTML 1.0 Transitional? This therefore pushing down content within table cells (i.e Hotmail in Firefox, Gmail in IE and Firefox). Has anyone else experienced this issue and know a way around it? Cheers
