  • Rails scalar query

    - by Craig
    I need to display a UI element (e.g. a star or checkmark) for employees that are 'favorites' of the current user (another employee). The Employee model has the following relationship defined to support this: has_and_belongs_to_many :favorites, :class_name => "Employee", :join_table => "favorites", :association_foreign_key => "favorite_id", :foreign_key => "employee_id" The favorites has two fields: employee_id, favorite_id. If I were to write SQL, the following query would give me the results that I want: SELECT id, account, IF( ( SELECT favorite_id FROM favorites WHERE favorite_id=p.id AND employee_id = ? ) IS NULL, FALSE, TRUE) isFavorite FROM employees Where the '?' would be replaced by the session[:user_id]. How do I represent the isFavorite scalar query in Rails? Another approach would use a query like this: SELECT id, account, IF(favorite_id IS NULL, FALSE, TRUE) isFavorite FROM employees e LEFT OUTER JOIN favorites f ON e.id=f.favorite_id AND employee_id = ? Again, the '?' is replaced by the session[:user_id] value. I've had some success writing this in Rails: ee=Employee.find(:all, :joins=>"LEFT OUTER JOIN favorites ON employees.id=favorites.favorite_id AND favorites.employee_id=1", :select=>"employees.*,favorites.favorite_id") Unfortunately, when I try to make this query 'dynamic' by replacing the '1' with a '?', I get errors. ee=Employee.find(:all, :joins=>["LEFT OUTER JOIN favorites ON employees.id=favorites.favorite_id AND favorites.employee_id=?",1], :select=>"employees.*,favorites.favorite_id") Obviously, I have the syntax wrong, but can :joins expressions be 'dynamic'? Is this a case for a Lambda expression? I do hope to add other filters to this query and use it with will_paginate and acts_as_taggable_on, if that makes a difference. edit errors from trying to make :joins dynamic: ActiveRecord::ConfigurationError: Association named 'LEFT OUTER JOIN favorites ON employees.id=favorites.favorite_id AND favorites.employee_id=?' was not found; perhaps you misspelled it? from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1906:in `build' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1911:in `build' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1910:in `each' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1910:in `build' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1830:in `initialize' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1789:in `new' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1789:in `add_joins!' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1686:in `construct_finder_sql' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1548:in `find_every' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:615:in `find'

  • Returning Arrays from .net web service to Java ME web service results in compile error of stub?

    - by sphereinabox
    So, I'm getting some compile errors on netbeans 6.5 generated web service code for a java ME client to a c# (vs2005) web service. I've trimmed my example significantly, and it still shows the problem, and not being able to return a collection of things is pretty much a deal-breaker. c# web service (SimpleWebService.asmx) <%@ WebService Language="C#" Class="SimpleWebService" %> using System; using System.Web; using System.Web.Services; using System.Web.Services.Protocols; [WebService(Namespace = "http://sphereinabox.com/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class SimpleWebService : System.Web.Services.WebService { [WebMethod] public CustomType[] GetSomething() { return new CustomType[] {new CustomType("hi"), new CustomType("bye")}; } public class CustomType { public string Name; public CustomType(string _name) { Name = _name; } public CustomType() { } } } WSDL (automatically generated by vs2005): <?xml version="1.0" encoding="utf-8"?> <wsdl:definitions xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:tns="http://sphereinabox.com/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" targetNamespace="http://sphereinabox.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"> <wsdl:types> <s:schema elementFormDefault="qualified" targetNamespace="http://sphereinabox.com/"> <s:element name="GetSomething"> <s:complexType /> </s:element> <s:element name="GetSomethingResponse"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="GetSomethingResult" type="tns:ArrayOfCustomType" /> </s:sequence> </s:complexType> </s:element> <s:complexType name="ArrayOfCustomType"> <s:sequence> <s:element minOccurs="0" maxOccurs="unbounded" name="CustomType" nillable="true" type="tns:CustomType" /> </s:sequence> </s:complexType> <s:complexType name="CustomType"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string" /> </s:sequence> </s:complexType> </s:schema> </wsdl:types> <wsdl:message name="GetSomethingSoapIn"> <wsdl:part name="parameters" element="tns:GetSomething" /> </wsdl:message> <wsdl:message name="GetSomethingSoapOut"> <wsdl:part name="parameters" element="tns:GetSomethingResponse" /> </wsdl:message> <wsdl:portType name="SimpleWebServiceSoap"> <wsdl:operation name="GetSomething"> <wsdl:input message="tns:GetSomethingSoapIn" /> <wsdl:output message="tns:GetSomethingSoapOut" /> </wsdl:operation> </wsdl:portType> <wsdl:binding name="SimpleWebServiceSoap" type="tns:SimpleWebServiceSoap"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="GetSomething"> <soap:operation soapAction="http://sphereinabox.com/GetSomething" style="document" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:binding name="SimpleWebServiceSoap12" type="tns:SimpleWebServiceSoap"> <soap12:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="GetSomething"> <soap12:operation soapAction="http://sphereinabox.com/GetSomething" style="document" /> <wsdl:input> <soap12:body use="literal" /> </wsdl:input> <wsdl:output> <soap12:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="SimpleWebService"> <wsdl:port name="SimpleWebServiceSoap" binding="tns:SimpleWebServiceSoap"> <soap:address location="http://localhost/SimpleWebService/SimpleWebService.asmx" /> </wsdl:port> <wsdl:port name="SimpleWebServiceSoap12" binding="tns:SimpleWebServiceSoap12"> <soap12:address location="http://localhost/SimpleWebService/SimpleWebService.asmx" /> </wsdl:port> </wsdl:service> </wsdl:definitions> Generated (netbeans) code that fails to compile, this was created going through the "Add - New JavaME to Web Services Client" wizard.

The errors are that string isn't defined (it's String in java, and besides I think this should be talking about CustomType anyway). private static string string_fromObject( Object obj[] ) { if(obj == null) return null; string result = new string(); return result; }

  • updating rails to 2.3.6

    - by Nik
    can you update your 2.3.5 app with just "gem update rails" and change the version # in environment.rb? I did that and lots of errors came out like in console just typing Post.all would show "undefined method `retrieve_connection' for nil:NilClass". Any ideas? By the way, I have these gems in my environment.rb config.gem "aws-s3", :version = "= 0.6.2", :lib = "aws/s3" config.gem "less" config.gem "authlogic" config.gem "be9-acl9", :source = "http://gems.github.com", :lib = "acl9" config.gem "hash_extension" config.gem "prawn"

  • Speed Problem with Wireless Connectivity on Cisco 877w

    - by Carl Crawley
    Having a bit of a weird one with my local LAN setup. I recently installed a Cisco 877W router on my DSL2+ connection and all is working really well.. Upgraded the IOS to 12.4 and my wired clients are streaming connectivity superfast at 1.3mb/s. However, there seems to be an issue with my wireless clients - I can't seem to stream any data across the local wireless connection (LAN) and using the Internet, whilst responsive enough isn't really comparable with the wired connection speed. For example, all devices are connected to an 8 Port Gb switch on FE0 from the Router with a NAS disk and on my wired clients, I can transfer/stream etc absolutely fine - however, transferring a local 700Mb file on my local LAN estimates 7-8 hours to transfer :( The Wireless config is as follows : interface Dot11Radio0 description WIRELESS INTERFACE no ip address ! encryption mode ciphers tkip ! ssid [MySSID] ! speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 channel 2462 station-role root rts threshold 2312 world-mode dot11d country GB indoor bridge-group 1 bridge-group 1 subscriber-loop-control bridge-group 1 spanning-disabled bridge-group 1 block-unknown-source no bridge-group 1 source-learning no bridge-group 1 unicast-flooding All devices are connected to the Gb Switch which is connected to FE0 with the following: Hardware is Fast Ethernet, address is 0021.a03e.6519 (bia 0021.a03e.6519) Description: Uplink to Switch MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output never, output hang never Last clearing of "show interface" counters never Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 14000 bits/sec, 19 packets/sec 5 minute output rate 167000 bits/sec, 23 packets/sec 177365 packets input, 52089562 bytes, 0 no buffer Received 919 broadcasts, 0 runts, 0 giants, 0 throttles 260 input errors, 260 CRC, 0 frame, 0 overrun, 0 ignored 0 input packets with dribble condition detected 156673 packets output, 106218222 bytes, 0 underruns 0 output errors, 0 collisions, 2 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out Not sure why I'm having problems on the wireless and I've reached the end of my Cisco knowledge...

  • Does resharper make you lazy?

    - by ForeverDebugging
    I've been looking at using resharper and from the reviews I've seen, people who start using it never go back. I'm wondering if using resharper helps you pick up errors when looking at code without resharper, or does it decrease this ability becaues you get use to relying on resharper to identify problems?

  • How to use EntityFramework connection string for Elmah?

    In ELMAH for logging errors to the database you can write: <errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="EducoparkEntities"/> However, if I use EntityFramework, this doesn't work because the connection string for EF contains metadata as well: <add name="EducoparkEntities" connectionString="metadata=res://*/EducoparkData.csdl|res://*/EducoparkData.ssdl|res://*/EducoparkData.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=(Local);Initial Catalog=...;User Id=...;Password=...;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient"/> So, how can I use the EntityFramework connection string in Elmah?

  • gcc compiling error on Solaris 10

    - by osman toker
    I want to compile a source code, but there are some compiling errors about __sync_xxx functions (__sync_bool_compare_and_swap etc.) GCC version on machine is 3.4.3 (it must be gcc 4.1 or over for supporting atomic builtins), so I have downloaded GCC v4.6, copied it to another directory (I didn't remove v3.4.3) then change the $PATH path for GCC but it doesn't work (the same error occurs). I want to ask that is only changing gcc path with export PATH=... enough for compiling with new GCC?

  • boost smart pointers and BOOST_NO_MEMBER_TEMPLATES

    After some struggling I managed to get boost smart pointers to build for Windows CE/Mobile at warning level 4. I found the least-resistance-way to get rid of compile errors and warnings to be #define BOOST_NO_MEMBER_TEMPLATES What does it actually mean? Did I sell my soul to the devil? Will all hell break loose when I actually use the types?

  • How do you keep track of your thought process ?

    I find it very hard to answer question like : "why did you implemented it this way?" or "what's the reason of using that instead of that?" usually because the implementation is the result of a long thought process and trials and errors. By the time i'm finished i can't recall every specific details. I wanted to know if you have some tips to keep track of your thought process and answer those question easily.
