  • How to set up two models having a has_many association with each other

    - by daz13
    I'm looking for a suggestion on how to set up two models, Teacher and Subject. A Teacher can have many Subjects, and a Subject can have many Teachers. Another thing to consider in the relationship between the two models is that a Teacher can create a Subject and add other Teachers to the Subject. I think I'm solid on the basics of the set up for each model: for teacher.rb: has_many :subjects for subject.rb: has_many :teachers and the teachers table should have a subject_id column and the subject table should have a teacher_id column. What I'm not sure about is how to set up the views (and corresponding controller methods) to allow the addition of a Teacher to a Subject. Any suggestions (or links to examples) are greatly appreciated. I haven't been able to find anything on this exact case.

  • One-to-many relationship related to many tables

    - by Andrey
    I have a scenario where: there are two (or more) tables that represent independent items. lets say Users and Companies Both of these tables need addresses stored. Each one can have one or more address In a normal 1 to many scenario Addresses table woudl just have a UserId or a CompanyId creating a normal 1 to many relationship. In this case i have a few approaches i can think of the Addresses table could have both a UserId and a CompanyId and only one would be used for each record. 2 keys could be used ObjectId and ObjectType So Object id would have a UserId or a CompanyId, and ObjectType woudl be User or Company Create an ObjectTable and add ObjectId to Users and Companies. Addresses would then have an OjbectId I do not really like any of these solutions. i am wondering what is the best approach here. On another note i will most likely user linqtosql for my data access layer.

  • Data manipulation without server side

    - by monczek
    Hi, I have to create a very simple webpage to show, filter and add data from not-yet-defined source (probably txt/xml/cvs). Records should be visible as a table, filtered using 3 criteria fields. There should be also possibility to add new records. My first thought was: XHTML + jQuery + csv2table + PicNet Table Filter. It does exactly what I want except adding rows - that is saving changes in source file (probably due to security risk). My question is - is there any possibility to do it without involving server side like asp.net, jee, php, sql? Source file is located on the server. Thanks for your ideas :-)

  • Creating new Entities from Stored Procedure

    - by SK
    I have a stored procedure that retrieves existing rows from a table and also creates includes new rows that match the table definition and mapped entity (.net 3.5 entity framework). These new rows are not written to the database in the stored procedure. The stored procedure executes, but the new rows that were created will not load the navigation properties sucessfully i.e. the rows that do not actually exist in the database. e.g. database rows: key, data, FK 1, xxx, a 2, xxx, b returned rows from stored procedure: key, data, FK 1, xxx, a 2, xxx, b 3, yyy, a 4, yyy, b The entity will load FK entities a and b for rows 1 and 2, but for rows 3 and 4 the FK entity is null. Do I somehow need to add the new rows to the data context? or turn off tracking?

  • rails respond_to and various forms of html responses

    - by lukewendling
    I often use respond_to do |format| ... end in Rails for my Restful actions, but I don't know what the ideal solution is for handling various forms of, say, html responses. For instance, view1 that calls action A might expect back html with a list of widgets wrapped in a UL tag, while view2 expects the same list of widgets wrapped in a table. How does one Restfully express that not only do I want back an html formatted response, but I want it wrapped in a table, or in a UL, OL, options, or some other common list-oriented html tag?

  • MySQL Insert Query Randomly Takes a Long Time

    - by ShimmerTroll
    I am using MySQL to manage session data for my PHP application. When testing the app, it is usually very quick and responsive. However, seemingly randomly the response will stall before finally completing after a few seconds. I have narrowed the problem down to the session write query which looks something like this: INSERT INTO Session VALUES('lvg0p9peb1vd55tue9nvh460a7', '1275704013', '') ON DUPLICATE KEY UPDATE sessAccess='1275704013',sessData=''; The slow query log has this information: Query_time: 0.524446 Lock_time: 0.000046 Rows_sent: 0 Rows_examined: 0 This happens about 1 out of every 10 times. The query usually only takes ~0.0044 sec. The table is InnoDB with about 60 rows. sessId is the primary key with a BTREE index. Since this is accessed on every page view, it is clearly not an acceptable execution time. Why is this happening? Update: Table schema is: sessId:varchar(32), sessAccess:int(10), sessData:text

  • alternative to lag SQL command

    - by mahen
    I have a table which has a table like this. Month-----Book_Type-----sold_in_Dollars Jan----------A------------ 100 Jan----------B------------ 120 Feb----------A------------ 50 Mar----------A------------ 60 Mar----------B------------ 30 and so on I have to calculate the expected sales for each month and book type based on the last 2 months sales. So for March and type A it would be (100+50)/2 = 75 For March and type B it is 120/1 since no data for Feb is there. I was trying to use the lag function but it wouldn't work since there is data missing in a few rows. Any ideas on this?

  • Efficient mapping for a particular finite integer set

    - by R..
    I'm looking for a small, fast (in both directions) bijective mapping between the following list of integers and a subset of the range 0-127: 0x200C, 0x200D, 0x200E, 0x200F, 0x2013, 0x2014, 0x2015, 0x2017, 0x2018, 0x2019, 0x201A, 0x201C, 0x201D, 0x201E, 0x2020, 0x2021, 0x2022, 0x2026, 0x2030, 0x2039, 0x203A, 0x20AA, 0x20AB, 0x20AC, 0x20AF, 0x2116, 0x2122 One obvious solution is: y = x>>2 & 0x40 | x & 0x3f; x = 0x2000 | y<<2 & 0x100 | y & 0x3f; Edit: I was missing some of the values, particularly 0x20Ax, which don't work with the above. Another obvious solution is a lookup table, but without making it unnecessarily large, a lookup table would require some bit rearrangement anyway and I suspect the whole task can be better accomplished with simple bit rearrangement. For the curious, those magic numbers are the only "large" Unicode codepoints that appear in legacy ISO-8859 and Windows codepages.

  • Retrieving Gtk::Widget's relative position: get_allocate() doesn't work

    - by a-v
    I need to retrieve the position of a Gtk::Widget relative to its parent, a Gtk::Table. Most sources (e.g. http://library.gnome.org/devel/gtk-faq/stable/x642.html) say that one needs to call Gtk::Widget::get_allocation(). However, the returned Gtk::Allocation object always contains x = -1, y = -1, width = 1, height = 1. I have to note that this happens before the Gtk::Table object is actually exposed and rendered. A call to show_all_children() or check_resize(), which I would expect to recalculate child widget geometry, doesn't help. What am I doing wrong? Thanks in advance.

  • PHP, MySQL - would results-array shuffle be quicker than "select... order by rand()"?

    - by sombe
    I've been reading a lot about the disadvantages of using "order by rand" so I don't need update on that. I was thinking, since I only need a limited amount of rows retrieved from the db to be randomized, maybe I should do: $r = $db->query("select * from table limit 500"); for($i;$i<500;$i++) $arr[$i]=mysqli_fetch_assoc($r); shuffle($arr); (i know this only randomizes the 500 first rows, be it). would that be faster than $r = $db->("select * from table order by rand() limit 500"); let me just mention, say the db tables were packed with more than...10,000 rows. why don't you do it yourself?!? - well, i have, but i'm looking for your experienced opinion. thanks!

  • How to select first entry of the day grouped by user in SQL

    - by mikepreble
    I've looked around and can't quite grasp the whole answer to this SQL query question needed to extract data from an MS Access 2000 table. Here's an example of what the table [Time Sub] looks like: CLIENT_ID, DATE_ENTERED, CODE, MINUTES 11111, 5/12/2008 3:50:52 PM, M, 38 11111, 5/12/2008 2:55:50 PM, M, 2 11714, 5/13/2008 1:15:32 PM, M, 28 11111, 5/13/2008 6:15:12 PM, W, 11 11112, 5/12/2008 2:50:52 PM, M, 89 11112, 5/12/2008 5:10:52 PM, M, 9 91112, 5/14/2008 1:10:52 PM, L, 96 11112, 5/12/2008 5:11:52 PM, M, 12 I need to select the first entry of each day per client that's NOT code L or W. I know this can be done in a SQL statement, but I just can't figure out how. I can get close, but never come up with the right output. Any help is appreciated. Thanks, Mike

  • Reduce text length to fit cell width in a smart manner

    - by Andrei Ciobanu
    Hello, I am in project where we are building a simple web calendar using Java EE technologies. We define a table where every row is an employee, and every column represents an hour interval. The table width and column widths are adjustable. In every cell we have a text retrieved from a database, indicating what the employee is doing / should do in that time interval. The problem is that sometimes the text in cells is getting bigger than the actual cell. My task is to make the text more "readable" by reducing it's length in a "smart way" so that it can fit in the cell more "gracefully". For example if initially in a cell I have: "Writing documents", after the resize I should retrieve: "Wrtng. dcmnts" or "Writ. docum." so that the text can fit well. Is there a smart way to do it ? Or removing vocals / split the string in two is enough ?

  • On saving a new record an associated id changes to 9 figure number

    - by Dave
    Hi, I have a table of venues, with each venue belonging to an area and a type. I recently dropped the table and added to it some addressline fields. I have re-migrated it but now the area_id field saves as a random? 9 figure number. Both the area_id and venuetype_id integers are created in the same way from the create new form and the venuetype_id saves as normal but not the area_id. Can anyone offer any help? whats shown in the console => [#<Venue id: 4, name: "sdf", addressline1: "", addressline2: "", addressline3 : "", addressline4: "", icontoppx: 234, iconleftpx: 234, area_id: 946717224, ven uetype_id: 8, created_at: "2011-03-17", updated_at: "2011-03-17 23:33:53">] irb(main):030:0> the area_id should be 8 in the above example.

  • How can I sum a group of sums? SQL-Sever 2008

    - by billynomates
    I have a query with a sum in it like this: SELECT Table1.ID, SUM(Table2.[Number1] + Table2.[Number2]) AS SumColumn FROM Table1 INNER JOIN Table3 ON Table1.ID = Table3.ID INNER JOIN Table2 ON Table3.ID = Table2.ID WHERE (Table2.[Something] = 'Whatever') GROUP BY Table1.ID, Table2.[Number1] , Table2.[Number2] and it gives me a table like this: ID SumColumn 67 1 67 4 70 2 70 6 70 3 70 6 80 5 97 1 97 3 How can I make it give me a table like this, where the SumColumn is summed, grouped by the ID column? ID SumColumn 67 5 70 17 80 5 97 4 I cannot GROUP BY SumColumn because I get an error (Invalid column name 'SumColumn'.) COALESCE doesn't work either. Thanks in advance. EDIT: Just grouping by the ID gives me an error: [Number1, Number2 and the other column names that I'm selecting] is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

  • MySQL query problem

    - by SaltLake
    I've got MySQL table CREATE TABLE stat ( ID int NOT NULL auto_increment PRIMARY KEY, TIMESTAMP_X timestamp DEFAULT CURRENT_TIMESTAMP, # ... some other fields ... ) which contains statistics about site visitors. For getting visits per hour I use SELECT hour(TIMESTAMP_X) as HOUR , count(*) AS HOUR_STAT FROM cms_webstat GROUP BY HOUR ORDER BY HOUR DESC which gives me | HOUR | HOUR_STAT | | 24 | 15 | | 23 | 12 | | 22 | 9 | | 20 | 3 | | 18 | 2 | | 15 | 1 | | 12 | 3 | | 9 | 1 | | 3 | 5 | | 2 | 7 | | 1 | 9 | | 0 | 12 | And I'd like to get following: | HOUR | HOUR_STAT | | 24 | 15 | | 23 | 12 | | 22 | 9 | | 21 | 0 | | 20 | 3 | | 19 | 0 | | 18 | 2 | | 17 | 0 | | 16 | 0 | | 15 | 1 | | 14 | 0 | | 13 | 0 | | 12 | 3 | | 11 | 0 | | 10 | 0 | | 9 | 1 | | 8 | 0 | | 7 | 0 | | 6 | 0 | | 5 | 0 | | 4 | 0 | | 3 | 5 | | 2 | 7 | | 1 | 9 | | 0 | 12 | How should I modify the query to get such result?

  • How to override <base> tag without removing the tag itself?

    - by sSmacKk
    I'm trying to add some internal links(in the format of a content table, to be able to facilitate webpage navigation) to this site in which a tag is used. Now obviously due to the base tag, every other relative tag will be relative to the base tag href. But in order for me to create this internal content table with the links pointing to different parts of the specific page, i need to get the default URL (before base tag is in effect) so the internal links can work properly. Is there a way to do get around the base tag and accomplish this? PS: if the question is unclear please don't hesitate to ask so i can reformulate Thanks in advance, :D :D

  • Order mysql results without identifier

    - by Alex Crooks
    Usually I would have a table field called ID on auto increment. That way I could order using this field etc. However I have no control over the structure of a table, and wondered how to get the results in reverse order to default. I'm currently using $q = mysql_query("SELECT * FROM ServerChat LIMIT 15"); However like I said there is no field I can order on, so is there a way to tell mysql to reverse the order it gets the results? I.e last row to first row instead of the default.

  • Implementing an ActiveRecord before_find

    - by thaiyoshi
    I am building a search with the keywords cached in a table. Before a user-inputted keyword is looked up in the table, it is normalized. For example, some punctuation like '-' is removed and the casing is standardized. The normalized keyword is then used to find fetch the search results. I am currently handling the normalization in the controller with a before_filter. I was wondering if there was a way to do this in the model instead. Something conceptually like a "before_find" callback would work although that wouldn't make sense on for an instance level.

  • MS Access Crashed an now all Form objects and code modules are missing

    - by owlie
    I was adding a form to our Access 07 db. I copied an existing form to use as a template, renamed it, and saved it. I opened a different form to check something and Access crashed. When I reopened the database it says: "Access has detected that this database is in an inconsistent state, and will attempt to recover the database." etc. When it reopened - all forms and reports were missing. Saved queries remain. The error message states that object recovery failures will be noted in a Recovery Errors table - but this table wasn't created. The links to the be database remained intact. The database is split - I was experimenting with a form on a front-end copy which might have something to do with it. Any ideas what would cause this (I can see loosing recent work - but nixing all form objects?!) And is there any chance of recovery?

  • Find the period of over speed ?

    - by Vimvq1987
    Just something interesting come in my mind. Assume that we have a table (in SQL Server) like this: Location Velocity Time What is the best way to determine over speed periods (speed barrier is defined) ? My first idea was loading the table into an array, and then iterate over array to find these periods: (Pseudo C# code) bool isOverSpeed = false; for (int i =0;i<arr.Length;i++) { if (!isOverSpeed) if (arr[i].Velocity > speedBarrier) { #insert the first record into another array. isOverSpeed = true; } if(isOverSpeed) if (arr[i].Velocity < speedBarrier) { #insert the record into that array isOverSpeed = false; } } It works, but somewhat "not very effectively". Is there a "smarter" way, such as a T-SQL query or another algorithm to do this?
