  • Reloading an object not working in rspec

    - by Eric Baldwin
    I am trying to test a controller method with the following code: it "should set an approved_at date and email the campaign's client" do @campaign = Campaign.create(valid_attributes) post :approve, id: @campaign.id.to_s @campaign.reload @campaign.approved_at.should_not be(nil) end However, when I run this test, I get the following error: Failure/Error: @campaign.reload ActiveRecord::RecordNotFound: Couldn't find Campaign without an ID When I run the analagous lines in the rails console, the reload works and the value is set as I need it to be. Why isn't reload working for me when I run the code in an rspec test?

  • Should the argument be passed by reference in this .net example?

    - by Hamish Grubijan
    I have used Java, C++, .Net. (in that order). When asked about by-value vs. by-ref on interviews, I have always done well on that question ... perhaps because nobody went in-depth on it. Now I know that I do not see the whole picture. I was looking at this section of code written by someone else: XmlDocument doc = new XmlDocument(); AppendX(doc); // Real name of the function is different AppendY(doc); // ditto When I saw this code, I thought: wait a minute, should not I use a ref in front of doc variable (and modify AppendX/Y accordingly? it works as written, but made me question whether I actually understand the ref keyword in C#. As I thought about this more, I recalled early Java days (college intro language). A friend of mine looked at some code I have written and he had a mental block - he kept asking me which things are passed in by reference and when by value. My ignorant response was something like: Dude, there is only one kind of arg passing in Java and I forgot which one it is :). Chill, do not over-think and just code. Java still does not have a ref does it? Yet, Java hackers seem to be productive. Anyhow, coding in C++ exposed me to this whole by reference business, and now I am confused. Should ref be used in the example above? I am guessing that when ref is applied to value types: primitives, enums, structures (is there anything else in this list?) it makes a big difference. And ... when applied to objects it does not because it is all by reference. If things were so simple, then why would not the compiler restrict the usage of ref keyword to a subset of types. When it comes to objects, does ref serve as a comment sort of? Well, I do remember that there can be problems with null and ref is also useful for initializing multiple elements within a method (since you cannot return multiple things with the same easy as you would do in Python). Thanks.

  • Prevent web2py from caching ?

    - by Joe
    Hi ! I'm working with web2py and for some reason web2py seems to fail to notice when code has changed in certain cases. I can't really narrow it down, but from time to time changes in the code are not reflected, web2py obviously has the old version cached somewhere. The only thing that helps is quitting web2py and restarting it (i'm using the internal server). Any hints ? Thank you !

  • A scripting langauge for Windows?

    - by WhyKiki
    I work in Windows and often find the need to code some script that manipulates files or basic string manipulation. Currently, I'm doing this using PHP but having a LAMP stack for this seems overkill. I've tried things like autoHotkey but the syntax and functionality is horrific. So I'm looking for a scripting with: a) a sane syntax b) lots and lots of built-in libraries, functions, etc c) minimal setup. Preferably, I would like to code and run the script from my app launcher of choice, Executor

  • Delphi: Which are the downsides of having unused units listed in the uses clause?

    - by user193655
    I use cnPack Uses cleaner, but in general which are the downsides of having useless units? I know some of them: 1) of course if the unit is never used across the full project there will be useless resource consuption 2) the code insight will give useless results 3) the code insight will be slower But imagine a simple case: I have a project with 2 forms, I use StrUtils in one of them but I declared StrUtils in both of them... Is there any downside in temrs of memory consumption in this case or not?

  • How can I know when QProcess wants to read input?

    - by mpcabd
    I'm implementing a compiler in my Compilers class, I'm using Qt & C++. After I have generated the machine code from the source code, I'm executing the virtual machine that will execute the call. I'm facing a problem here, I'm using readyRead() signal to get output from the virtual machine, but how can I know that the virtual machine wants to read data from the user? I wanna show the user an input dialog each time the machine asks for input.

  • Retrieving Data in A NSTableView

    - by Heisennberg
    I have a three column Table View populated by two NSMutableDictionaries which share the same keys (ie key | value1 | value2 ) with dict1(key,value1) and dict2(key,value2). I want to manually enter data in the third column and create the key/value objects in dict2. But when I do that, my code picks the wrong key :S Here's the code for the delegate : - (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { if ([[aTableColumn identifier] isEqualToString:@"value2"]) { [dict2 setValue:anObject forKey:[[[aTableView tableColumnWithIdentifier:@"key"] dataCellForRow:rowIndex] stringValue ]]; } } Any idea ?
