ruby-1.9.3

问题 This question already has answers here : No named parameters in Ruby? (4 answers) Closed 5 years ago . I wonder why named parameters don't work as I expect. def my_method(var1, var2 = 1, var3 = 10) puts var1, var2, var3 end my_method(999, var3 = 123) The output 999 123 10 instead of (at least, as I guess should be): 999 1 123 So, what should I do to use named parameters? P.S. When I use the hash, it's not what I'm looking for yet: def my_method(var1, vars = {var2: 1, var3: 10} ) puts var1,

问题 I have upgraded by project from ree-1.8.7 to 1.9.2p429. I have an attribute in my devise model named silhouette_user_id. In views and occasionally in my ruby code, calling current_user.silhouette_user_id returns a different (and WRONG) value than current_user[:silhouette_user_id] which returns the right value. Though I could search and replace to fix this, I'm worried that other attributes will behave the same way. This is a LARGE project and I really need to determine why this is happening.

问题 I'm having problems using delayed_job (3.0.3) with ruby 1.9.3. Previously we were using ruby 1.8.7 which comes with yaml syck parser which read all the attributes that are set for a ruby object (including attr_accessors) but with the upgrade to 1.9.3 the yaml parser was switched to psych (which was re-written) and it doesn't take into account any attributes except those persisted in the database. How can we make psych to take the attr_accessors into account as well. I tried to switch to syck

问题 I have rvm, passenger, ruby 1.9.3, nginx but I now get this error Cannot spawn application '/path/to/my/app': Could not read from the spawn server: Connection reset by peer (104) I have passenger_root set to the output of passenger-config --root and ruby-1.9.3-p125 for passenger_ruby I did have to do rvmsudo passenger-install-nginx-module because passenger kept trying to install with 1.8.7 support rather than 1.9.3 i've even set spawn mode to conservative. Is there anything I'm missing out?
