  • How do I override file.write() under Python 3?

    - by Sorin Sbarnea
    Below works on Python 2.6 but on Python 3.x it doesn't: old_file_write = file.write class file(): def write(self, d): if isinstance(d, types.bytes): self.buffer.write(d) else: old_file_write(d) # ... do something like f = open("x") f.write("...") The problems is that with Python 3.x the first like will generate an error: NameError: name 'file' is not defined How can I make this work on Python 3.x? PS. In fact I'm looking for a solution that will work on both versions.

  • 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. The area and venuetype id's are slected from dropdown boxes on the new venue form. new form <%= form_for @venue do |f| %> <p>name: <br> <%= f.text_field :name %></p> <p>top: <br> <%= f.text_field :icontoppx %></p> <p>left: <br> <%= f.text_field :iconleftpx %></p> <p>addressline1: <br> <%= f.text_field :addressline1 %></p> <p>addressline2: <br> <%= f.text_field :addressline2 %></p> <p>addressline3: <br> <%= f.text_field :addressline3 %></p> <p>addressline4: <br> <%= f.text_field :addressline4 %></p> <p>area: <br> <%= f.collection_select(:area_id, Area.all, :id, :name) %></p> <p>venuetype: <br> <%= f.collection_select(:venuetype_id, Venuetype.all, :id, :name) %></p> <br><br> <div class="button"><%= submit_tag %></div> <% end %> Areas table class CreateAreas < ActiveRecord::Migration def self.up create_table :areas do |t| t.string :name t.timestamps end end def self.down drop_table :areas end end Thanks very much for any help!

  • How do I call a non-public method of a public class in Clojure?

    - by sramsay
    I'm calling the twitter4j library using Clojure like so: (def twitter (. (TwitterFactory.) getInstance)) This works fine when I call it as a script. But when I use gen-class, I get: java.lang.IllegalArgumentException: Can't call public method of non-public class: public java.lang.Object twitter4j.TwitterFactoryBase.getInstance() Is there a workaround for this?

  • Python: How should I make instance variables available?

    - by swisstony
    Suppose I have: class myclass: def __init__(self): self.foo = "bar" where the value of foo needs to be available to users of myclass. Is it OK to just read the value of foo directly from an instance of myclass? Should I add a get_foo method to myclass or perhaps add a foo property? What's the best practice here?

  • How to tell Ruby not to serialize an attribute or how to overload marshal_dump properly?

    - by GregMoreno
    I have an attribute in my AR:B that is not serializeable. o = Discussion.find(6) Marshal.dump(o) TypeError: no marshal_dump is defined for class Proc from (irb):10:in `dump' I know the culprit and what I want is to set this variable to nil before any serialization takes place. I can do this but I'm stuck with the proper way to override marshal_dump def marshal_dump @problem = nil # what is the right return here? end Or is there is way to tell Ruby or AR not to serialize an object?

  • Ruby parse order

    - by bresc
    Hi, given this code: class Foo def bar return Bar.new end end class Bar ... end I get this error: NameError: uninitialized constant Bar This obviously works if I put Bar before Foo but that is not a real solution though. Any ideas on how to solve this without considering the order? Many thanks.

  • Ruby hash value truthiness and symbols

    - by John Topley
    Could somebody please explain why the variable named foo remains true in the code below, even though it's set to false when the method is called? And why the symbol version behaves as expected? def test(options = {}) foo = options[:foo] || true bar = options[:bar] || :true puts "foo is #{foo}, bar is #{bar}" end >> test(:foo => false, :bar => :false) foo is true, bar is false I've only tried this using Ruby 1.8.7.

  • Exercise 7.9 in "How to Think Like a Computer Scientist (python)" measuring occurrences of a character in a string

    - by Abie
    The question is how to write a program that measures how many times a character appears in a string in a generalizable way in python. The code that I wrote: def countLetters(str, ch): count=0 index=0 for ch in str: if ch==str[index]: count=count+1 index=index+1 print count when I use this function, it measures the length of the string instead of how many times the character occurs in the string. What did I do wrong? What is the right way to write this code?
