  • rails separate login for an api

    - by Squadrons
    I have a very simple api that is part of a rails app that requires logging in. I just need a way to make the api part accessible with a simple form that allows the user to enter parameters like a key (just a simple one stored in the DB, no OAuth or anything), a userId to find and return a user via json, and maybe some other parameters like asking for their schedule. How can I keep this seperate from the rest of the app, making it a public facing form that will grant access only to the api? Thanks.

  • Can a webflow's action state have multiple redirects on success?

    - by callie16
    Say, I have this type of webflow: def myFlow = { state1 { } on("next").to("stateAct") stateAct { action { ... DB stuff ... } } on("success").to("state2") state2 { } on("prev").to("state1") } Now, the contents of "stateAct" is common between state1 and state2. Meaning, if I press "next" from state1, I need to pass by stateAct before I can go to state2 (which is the current implementation) and if I press "prev" in state2, I need it to pass by stateAct before it goes to state1. Obviously, in the sample webflow above, it doesn't do the latter. So, my question is, is there a way to detect in stateAct who called it (state1 or state2) so that I can redirect accordingly on "success"? Or something similar to that behavior? Thanks! -Lee

  • How to save coordinates with Google Map?

    - by Pavel
    Hey everyone. I'm currently developing an app which uses tabs and google map. What I want to do is to get the gps positions, say 3, and store them in sql db (which I'm already doing) and then display them on the map. I already created canvas, added to overlay but those points disappear when I'm changing tabs so I thought if there is a way to somehow store those coords with google map so I can retrieve them and display them nicely whenever I'm clicking the "map tab"? Please can anyone help?

  • How to introduce multi-column constraint with JPA annotations?

    - by plouh
    I am trying to introduce a multi-key constraint on a JPA-mapped entity: public class InventoryItem { @Id private Long id; @Version private Long version; @ManyToOne @JoinColumn("productId") private Product product; @Column(nullable=false); private long serial; } Basically (product, serial) pair should be unique, but I only found a way to say that serial should be unique. This obviously isn't a good idea since different products might have same serial numbers. Is there a way to generate this constraint via JPA or am I forced to manually create it to DB?

    - by suomee
    I have a a mysql db with myisam engine. Along with many other table I have this table "et" which has around 8137037 records. I have created indexes (individual index of column hname and pnum, it did not help much later created joint index of hname and pnum and it help execute within a second)such that queries like "select st from et where hname='name' and pnum='1' limit 1;" execute fast (with in a second) but the problem is I must execute this query "select st from et where hname='name' and pnum='1' order by id limit 1" where id is the primary key of the table and this query sometimes take 145 seconds :( how can i resolve this issue?

  • Codeigniter passing variable to URL

    - by CyberJunkie
    I have a list of posts and an edit link for each. When clicking edit it goes to a page where I can edit the specific post I clicked on. For this I will have to pull from the db the id of the post. Would this be the correct way to do it? <a href="<?php echo site_url("post/edit/$row->id"); ?>">Edit</a> post is my controller, edit is my function, and $row->id should pull the id of the post.

  • All PHP files getting hacked

    - by nsearle
    Hey All, Like always, just want to say thank you for all of the help and input in advance. I have a particular site that I am the web developer for and am running into a unique problem. It seems that somehow something is getting into every single PHP file on my site and adding some malware code. I have deleted the code from every page multiple times and changed FTP and DB passwords, but to no avail. The code that is added looks like this - eval(base64_decode(string)) - which the string is 3024 characters. Not sure if anyone else has ran into this problem or if any one has ideas on how I can secure my php code up. Thanks again.

  • c# How to make linq master detail query for 0..n relationship?

    - by JK
    Given a classic DB structure of Orders has zero or more OrderLines and OrderLine has exactly one Product, how do I write a linq query to express this? The output would be OrderNumber - OrderLine - Product Name Order-1 null null // (this order has no lines) Order-2 1 Red widget I tried this query but is not getting the orders with no lines var model = (from po in Orders from line in po.OrderLines select new { OrderNumber = po.Id, OrderLine = line.LineNumber, ProductName = line.Product.ProductDescription, } ) I think that the 2nd from is limiting the query to only those that have OrderLines, but I dont know another way to express it. LINQ is very non-obvious if you ask me!

  • Forcing LINQ to SQL to make one single call for all child rows

    - by zaph0d
    Let say I have a method (example taken from another post): public IQueryable<CityBlock> GetCityBlocks(){ var results = from o in db.city_blocks let buildings = GetBuildingsOnBlock(o.block_id) //returns Iqueryable select new CityBlock { BuildingsOnBlock = buildings, BlockOwner = o.block_owner }; return results; } In the calling method I add Skip() and Take() methods plus some filtering and then do a ToList(). The trouble is that I am getting dozens of database calls - one for all the city blocks and then a separate one for each building. Is there a way that I can refactor this code to just make two calls: one for the city blocks and one for all the buildings

  • Linq.Where-to-SQL on a text field comparing to a list of values

    - by StampedeXV
    Customer.text is a field in an T-SQL DB (that I do not control and thus may not alter) of type "text". I'd like to do something like this: List<string> compare = new List<string>(); compare.Add("one"); compare.Add("two"); var q = from t in customer where t.text.Contains( compare.First()) select t; this will work. But now I'd like to do something like: (!NOT WORKING!) var q = from t in customer where compare.Contains( t.text ) select t; How can I achieve this? Is it even possible?

  • Windows Multiple User Application Best Practices

    - by Burt
    I am developing a WPF application that will hook into a SQLLite database and I have a number of reservations around multiple users: When I install my application should I assume that each windows user account will mean only one user of my application or should I include a login for my app (drawback is that the user will have to log in all the time) If I am supporting multiple users how do I handle a new user account i.e. on application start of the new account should I set up a new user in the DB Are there any other gotchas around this area, it isn't something I have really had to worry about before. Thanks in advance, B

  • Session State ArrayList in Shopping Cart ASP.NET

    - by user330342
    Hi guys, I'm creating a shopping cart application and I'm having some issues with implementing a session state for my arraylist. in my page load i declared if (Session["Cart"] == null) { Session["Cart"] = new ArrayList(); } else { ArrayList cart = (ArrayList)Session["Cart"]; } to create the session if it doesn't exist yet. then i have an event handler for a button to add items to the arraylist protected void onClick_AddBooking(object sender, EventArgs e) { int ClassID = Convert.ToInt32(Request.QueryString.Get("Class_Id")); ArrayList cart1 = new ArrayList(); cart1 = Session["Cart"]; cart1.Add(ClassID); i'm guessing i just don't know how to handle session states yet, thus the confusion. I'm essentially storing the class_ID then when the student confirms i'll store that to the DB and associate that ID with the Class Details. Thanks in advance guys!

  • Select n+1 problem

    - by Arnis L.
    Foo has Title. Bar references Foo. I have a collection with Bars. I need a collection with Foo.Title. If i have 10 bars in collection, i'll call db 10 times. bars.Select(x=x.Foo.Title) At the moment this (using NHibernate Linq and i don't want to drop it) retrieves Bar collection. var q = from b in Session.Linq<Bar>() where ... select b; I read what Ayende says about this. Another related question. A bit of documentation. And another related blog post. Maybe this can help? What about this? Maybe MultiQuery is what i need? :/ But i still can't 'compile' this in proper solution. How to avoid select n+1?

  • Minimizing calls to database in rails

    - by ming yeow
    Hi guys, i am familiar with memcached and eager loading, but neither seems to solve the problem i am facing. My main performance lag comes from hundreds of data retrieval calls from the database. The tricky thing is that I do not know which set of users i need to retrieve until i have several steps of computation. I can refactor my code, but i was wondering how you experts handle this situation? I think it should be a fairly common situation def newsfeed - find out which users i need - retrieve those users via DB - find out which events happened for these users - for each of those events - retrieve new set of users - find out which groups are relevant - for each of those groups - retrieve new set of users - etc, etc end

  • iOS Development: Can I store an array of integers in a Core Data object without creating a new table to represent the array?

    - by BeachRunnerJoe
    Hello. I'm using Core Data and I'm trying to figure out the simplest way to store an array of integers in one of my Core Data entities. Currently, my entities contain various arrays of objects that are more complex than a single number, so it makes sense to represent those arrays as tables in my DB and attach them using relationships. If I want to store a simple array of integers, do I need to create a new table with a single column and attach it using a one-to-many relationship? Or is there a more simple way? Thanks in advance for your wisdom!

  • Simple PHP query question: LIKE

    - by pg
    When I replace $ordering = "apples, bananas, cranberries, grapes"; with $ordering = "apples, bananas, grapes"; I no longer want cranberries to be returned by my query, which I've written out like this: $query = "SELECT * from dbname where FruitName LIKE '$ordering'"; Of Course this doesn't work, because I used LIKE wrong. I've read through various manuals that describe how to use LIKE and it doesn't quite make sense to me. If I change the end of the db to "LIKE "apples"" that works for limiting it to just apples. Do I have to explode the ordering on the ", " or is there a way to do this in the query?

  • Prevent log4net to send duplicate issues via SMTP

    - by jrEwing
    Hi, we have bridged our log4net with Jira using SMTP. Now we are worried that since the site is public what could happen to the Jira server if we get alot of issues in the production environment. We have already filtered on Critical and Fatal, but we want to see either some acumulator service on log4net or a plain filter which identifies repeating issues and prevents them from being sent via Email. Preferably without having to change the error reporting code, so a config solution would be best. I guess dumping the log into a db and then create a separate listener some smart code would be a (pricy) alternative.

  • RSpec leaves record in test database

    - by DMiller
    Whenever I run a user test, RSpec leaves the Fabricated user in the test database after the test has completed, which is messing up my other tests. I will do a rake db:test:prepare, but when I run my tests again, the record is recreated in my database. I have no idea why this is happening. It only happens with user objects. In my spec_helper file I even have: config.use_transactional_fixtures = true Here is an example test that creates a record: it "creates a password reset token for the user" do alice = Fabricate(:user) post :create, email: alice.email expect(assigns(alice.password_reset_token)).to_not eq(nil) end Fabricator: Fabricator(:user) do email { Faker::Internet.email } password 'password' name { Faker::Name.name } end Could this have anything to do with my users model?

  • 'Caching' a large table in ASP.NET

    - by TheNewGuy
    I understand that each page refresh, especially in 'AjaxLand', causes my back-end/code-behind class to be called from scratch... This is a problem because my class (which is a member object in System.Web.UI.Page) contains A LOT of data that it sources from a database. So now every page refresh in AjaxLand is causing me to making large backend DB calls, rather than just to reuse a class object from memory. Any fix for this? Is this where session variables come into play? Are session variables the only option I have to retain an object in memory that is linked to a single-user and a single-session instance?

  • Fastest way to compare Objects of type DateTime

    - by radbyx
    I made this. Is this the fastest way to find lastest DateTime of my collection of DateTimes? I'm wondering if there is a method for what i'm doing inside the foreach, but even if there is, I can't see how it can be faster than what i all ready got. List<StateLog> stateLogs = db.StateLog.Where(p => p.ProductID == product.ProductID).ToList(); DateTime lastTimeStamp = DateTime.MinValue; foreach (var stateLog in stateLogs) { int result = DateTime.Compare(lastTimeStamp, stateLog.TimeStamp); if (result < 0) lastTimeStamp = stateLog.TimeStamp; // sæt fordi timestamp er senere }

  • Controlling new features in Spring/Apache tomcat

    - by HeretoLearn
    Is there a good way to manage roll out of new software in Spring/Tomcat configuration. The problem I am trying to address is being able to rollback newly deployed software provided there are no hard dependencies on other moving pieces. For example changed the guts of an algorithm and now want to deploy the new software with the new change off by default and then turning it on on one of the web servers. An obvious way is to build a session object which has a map of key-value pairs(property,bool) which is populated from a db on a session startup and then the value is persisted for that session. This is so that if the value is reverted back existing sessions which started with the original value retain the original value and giving application consistency. Is there a more obvious inbuilt mechanism to do this?

  • How to store coordinates in a database

    - by Tim
    Hello all! I have a Flex GUI where I have to place quadrate elements. The position of these elements need to be stored into a database. So I can create two integer fields in the db table x and y. Also I need an angle, because the user can rotate these elements, so I can also make a int (int is okay, I do not need a double value therefore). As a ORM, I use Hibernate. But the question is, if creating three integer fields is the best way to handle this. Perhaps someone can tell me if this will be okay or if there are better ways? Thanks a lot in advance & Best Regards.
