  • last_login_at not working (null) w/ Authlogic Magic Columns...

    - by bgadoci
    I am using the Authlogicgem for authentication and most of it seems to be working great. Authlogic provides several columns that you can add to your Users table (for example) that it knows to fill in if they are present. i.e. login_count, current_login_ip, last_request_at and last_login_at. All seem to be working fine with the exception of the last_login_at field which is null for each user. Is there anything specific that could be causing this perhaps having to do with the user sessions, etc? I can post code if needed but wasn't sure what would relate to this.

  • SQL for total count and count within that where condition is true

    - by twmulloy
    Hello, I have a single user table and I'm trying to come up with a query that returns the total count of all users grouped by date along with the total count of users grouped by date who are of a specific client. Here is what I have thus far, where there's the total count of users grouped by date, but can't seem to figure out how to get the count of those users where user.client_id = x SELECT user.created, COUNT(user.id) AS overall_count FROM user GROUP BY DATE(user.created) trying for a row result like this: [created] => 2010-05-15 19:59:30 [overall_count] => 10 [client_count] => (some fraction of overall count, the number of users where user.client_id = x grouped by date)

  • Database design: How should I add an information which can apply to several tables

    - by Stefan
    I am constructing a database System using Mysql, this will be an application of about 20 tables. The system contains information on farmers, we work with organic certification and need to record a lot of info for that. In my system, there are related parent-child tables for farmers, producing years and fields/areas - it's a simple representation of the real world in which farmers farm crops on their fields. I now need to add several status flags for each one of these levels: a farmer can be certified, or his field can be, or the specific year can be; each of these flags has several states and can occur a number of times. The obvious solution to this would be to add a child table to every one of these tables, and define the states there. What I wonder if there is an easier way to do this to avoid getting to many tables? Where/how would be best practise to keep that data?

  • Fastest tr:hover method

    - by Alex
    What is the single fastest method for table row hover css change? I've tried jQuery (onmouseover/out) and CSS with tr:hover, but once I make my page fullscreen (1920x1200) the performance on my grid is getting just sluggish enough to give the entire page a feel of being sub-par. That's on a grid with 25 rows, and some spans and divs per row. I've tried IE and Google Chrome. Is there another, faster method? What is generally considered the fastest method across browsers for doing hover CSS changes?

  • c# hierarchy collection library? - anyone know of one (e.g. GetDirectChildren, GetAllChildren, GetPa

    - by Greg
    Hi, Does anyone know of a solid C# library / approach to manage a hierarchy/web type collection? This would be a library that would basic consist of the concept of nodes & relationships, for example to model web pages/files linked under a URL, or modeling IT infrastructure. It would have key methods such as: Node.GetDirectParents() Node.GetRootParents() Node.GetDirectChildren() Node.GetAllChildren() So it's smarts would include the ability to "walk the tree" of nodes based on the relationships when someone does ask for "give me all the children under this node" for example. It ideally include a persistence layer, to save/retrieve such data to/from a databases (e.g. with a Nodes and Relationships table). Thanks

  • ExtJS Grid slow with 3000+ records

    - by Oliver Watkins
    I am using ExtJS Grid and its getting pretty slow with 3000+ records. Sorting takes about 4 seconds. Compared to other more Javascript tables, this is pretty slow. I am thinking maybe to use pagination in my table. However after reading the documentation, I am still a bit unsure about how pagination works in extjs. Does this pull data from the server each time u turn a page? I would prefer that wasn't the case. I would prefer the 3000 records are saved in the browser and then what is rendered is just a portion of those rows. Also I am using Extjs version 4.2.1. If I upgrade to version 5. will I get some performance improvements?

  • My Linq to Sql Insert code seems to work fine but I don't get a record in the database

    Here is my code. In the debugger, I can see that the code is running. No errors are thrown. But, when I go back to the table, no row has been inserted. What am I missing?? protected void submitButton_Click(object sender, EventArgs e) { CfdDataClassesDataContext db = new CfdDataClassesDataContext(); string sOfficeSought = officesSoughtDropDownList.SelectedValue; int iOfficeSought; Int32.TryParse(sOfficeSought, out iOfficeSought); Account act = new Account() { FirstName = firstNameTextBox.Text, MiddleName = middleNamelTextBox.Text, LastName = lastNameTextBox.Text, Suffix = suffixTextBox.Text, CampaignName = campaignNameTextBox.Text, Address1 = address1TextBox.Text, Address2 = address2TextBox.Text, TownCity = townCityTextBox.Text, State = stateTextBox.Text, ZipCode = zipTextBox.Text, Phone = phoneTextBox.Text, Fax = faxTextBox.Text, PartyAffiliation = partyAfilliatinoTextBox.Text, EmailAddress = emailTextBox.Text, BankName = bankNameTextBox.Text, BankMailingAddress = bankAddressTextBox.Text, BankTownCity = bankTownCityTextBox.Text, BankState = bankStateTextBox.Text, BankZip = bankZipTextBox.Text, TreasurerFirstName = treasurerFirstNameTextBox.Text, TreasurerMiddleName = treasurerMiddleNamelTextBox.Text, TreasurerLastName = treasurerLastNameTextBox.Text, TreasurerMailingAddress = treasurerMailingAddressTextBox.Text, TreasurerTownCity = treasurerTownCityTextBox.Text, TreasurerState = treasurerStateTextBox.Text, TreasurerZipCode = treasurerZipTextBox.Text, TreasurerPhone = treasurerPhoneTextBox.Text //OfficeSought = iOfficeSought }; act.Suffix = suffixTextBox.Text; db.SubmitChanges(); }

  • Connecting data to a GUI - OOP

    - by tau
    I have an application with several graphs and tables on it. I worked fast and just made classes like Graph and Table that each contained a request object (pseudo-code): class Graph { private request; public function setDateRange(dateRange) { request.setDateRange(dateRange); } public function refresh() { request.getData(function() { //refresh the display }); } } Upon a GUI event (say, someone changes the date range dropdown), I'd just call the setters on the Graph instance and then refresh it. Well, when I added other GUI elements like tables and whatnot, they all basically had similar methods (setDateRange and other things common to the request). What are some more elegant OOP ways of doing this? The application is very simple and I don't want to over-architect it, but I also don't want to have a bunch of classes with basically the same methods that are just routing to a request object. I also don't want to set up each GUI class as inheriting from the request class, but I'm open to any ideas really.

  • using KVO to update an NSTableView filtered by an NSPredicate

    - by KingRufus
    My UI is not updating when I expect it to. The application displays "projects" using a view similar to iTunes -- a source list on the left lets you filter a list (NSTableView) on the right. My filters update properly when they are examining any simple field (like name, a string), but not for arrays (like tags). I'm removing a tag from one of my objects (from an NSMutableArray field called "tags") and I expect it to disappear from the list because it no longer matches the predicate that is bound to my table's NSArrayController. ProjectBrowser.mm: self.filter = NSPredicate* srcPredicate = [NSPredicate predicateWithFormat:@"%@ IN %K", selectedTag, @"tags"]; Project.mm: [self willChangeValueForKey:@"tags"]; [tags removeAllObjects]; [self didChangeValueForKey:@"tags"]; I've also tried this, but the result is the same: [[self mutableArrayValueForKey:@"tags"] removeAllObjects]; Interface Builder setup: a ProjectBrowser object is the XIB's File Owner an NSArrayController (Project Controller) has its Content Array bound to "File's Owner".projects Project Controller's filter predicate is bound to "File's Owner".filter NSTableView's column is bound to "Project Controller".name

  • R storing a complex search as a string

    - by Tahnoon Pasha
    Hi I'm working with a large data frame that I frequently need to subset in different combinations of variables. I'd like to be able to store the search in a string so I can just refer to the string when I want to see a subset. x = read.table(textConnection(" cat1 cat2 value A Z 1 A Y 2 A X 3 B N 2"),header=T,strip.white=T) search_string="cat1== 'A' & cat2=='Z'" with(x,subset(x,search)) doesn't work. What I'd be looking for is the result of a search similar to the one below. with(x,subset(x,cat1=='A' & cat2=='Z')) I'd prefer not to just create multiple subsetted data frames at the start if another solution exists. Is there a simple way to do what I'm trying?

  • how to model a many to many relationship

    - by Maulin
    Here is the scenario, Articles have many Comments Users can write many Comments for many Articles The comments table contains both user_id article_id as foreign keys My models are set up like so class User < ActiveRecord::Base has_many :comments has_many :articles, :through => :comments class Article < ActiveRecord::Base has_many :comments has_many :users, :through => :comments class Comment < ActiveRecord::Base belongs_to :users belongs_to :articles My routes.rb has the following code map.resources :articles, :has_many => :comments map.resources :users, :has_many => :comments which produces the following routes new_article_comment edit_article_comment new_user_comment edit_user_comment etc... This is not what I want (atleast not what I think I want), since comments must always be related to users and article, how can I get a route like so new_user_article_comment edit_user_article_comment Then I could just do new_user_article_comment_path([@user, @article]) to create a new comment

  • MySQL query for initial filling of order column

    - by Sejanus
    Sorry for vague question title. I've got a table containing huge list of, say, products, belonging to different categories. There's a foreign key column indicating which category that particular product belongs to. I.e. in "bananas" row category might be 3 which indicates "fruits". Now I added additional column "order" which is for display order within that particular category. I need to do initial ordering. Since the list is big, I dont wanna change every row by hand. Is it possible to do with one or two queries? I dont care what initial order is as long as it starts with 1 and goes up. I cant do something like SET order = id because id counts from 1 up regardless of product category and order must start anew from 1 up for every different category.

  • What's the best way to share one Entity Framework 4 data model among multiple applications (meant to

    - by Ivan
    A project (a "solution" to say in VS terms) of mine consists of an ASP.Net 4 Dynamic Data Entities web application, some WinForms applications, some WPF applications, some services. All they are intended to work with one SQL Server database, generated from an Entity Framework 4 model as table-per-type, with lots of inheritance and multiple self-referencing relations. Where do I best put my model? In a separate class library, a copy in every project, in one project, etc. What naming should I best use? Is it good idea to name it MySolution.MyClassLibrary.MySolutionEntities, or just MySolutionEntities or just MySolution? Can you share any useful experience on this subject?

  • Filter the datagridview column based on the current row of another column in C#

    - by user286546
    I have a datagridview that is populating columns from different table. I want to filter the column based on another column of the current row. I tried to use the cell enter event of the datagridview and then filtered the column by filtering the binding source on the column of the current row. private void lINKDataGridView_CellEnter(object sender, DataGridViewCellEventArgs e) { this.pROBLEMBindingSource.Filter = "item_id = " + this.lINKDataGridView.Rows[e.RowIndex].Cells[dataGridViewTextBoxColumn4.Index].Value + ""; } This is how I am filtering the "problem " binding source on the cell enter event of the datagridview . It is working fine but I am getting an error- being: System.ArgumentException: DataGridViewComboBoxCell value is not valid. Any suggestion

  • mysql LAST_INSERT_ID() used with multiple records INSERT statement

    - by bogdan
    Hello, If i insert multiple records with a loop that executes a single record insert, the last insert id returned is, as expected, the last one... but if i do a multiple records insert statement: INSERT INTO people (name,age) VALUES('William',25),('Bart',15),('Mary',12); let's say the three above are the first records inserted in the table...after the insert statement i expected last insert id to return 3, but it returned 1...the first insert id for the statement in question... So can someone please confirm if this is the normal behavior of LAST_INSERT_ID() in the context of multiple records INSERT statements...so i can base my code on it thanks :)

  • MySQL, join one item to multiple items in a single query

    - by bschaeffer
    Say I've got two tables. One contains a list of items, and one contains pictures of the items. Something like this: Items +----+---------+ | id | name | +----+---------+ | 1 | oranges | | 2 | apples | +----+---------+ Pictures +----+---------+ | id | item_id | +----+---------+ | 1 | 1 | | 2 | 2 | | 3 | 2 | +----+---------+ My question is this: is it possible in a single query to select item 2 from Items and join all the rows in the Pictures table whose item_id references that same id? I am sure I've tried almost everything I can think of, but nothing is coming to mind. I apologize if the answer to this is simple, but It's just escaping me right now.

  • ASP.NET calendar drawing control

    I want to make a simple ASP.NET page that draws a months from a calendar and highlights given dates. (I'm not looking for a date picker.) What I have is a list of DateTime values and I need to display them a a nice way. Given that I'm a total beginner with ASP, simpler really is better. (I'd rather not, I'm willing to hack together something with StringBuilder and <table> if it's easier). p.s. I have no budget, so non-free controls will only be of use to other readers.

  • How may I see the data in the Oracle view like I see it through the application ?

    when I navigate through the Oracle application with my application user and the right responsibility, I see the data. I use the "record history" menu to see which table/view is used by application. So, I got PA_EXPEND_ITEMS_ADJUST2_V. When I'm connected with apps user in a sqlplus session, SELECT * FROM PA_EXPEND_ITEMS_ADJUST2_V gives me 0 rows. I guess that there's something is misconfigurated with the apps but what ? How may I view the rows of PA_EXPEND_ITEMS_ADJUST2_V using apps user in a sqlplus session ? How may I see the data in the Oracle view like I see it through the application ?
