rails read the file and store the database -

- 

       saved  .rb file in app/component/text.rb. want read , store database.

in file has 5 rows , table have 5 rows.i want save line line.you can understand question.i use mysql database.

  please me....

thanks, kingston.s

i missed rails- , ruby-version, operating system use , clear problem description...anyway

assuming meant database have 5 fields , want read , write record file:

assuming file contain record model "apple "with fields id, title , description.

read new apple file:

indexes = [:id, :title, :desc].reverse # careful data saved reverse because pop takes last element first record_params = {}  handle = file.open("apple.record","r") handle.lines.each |line|   record_params[indexes.pop]=line.chomp #use chomp rid of trailing \n end handle.close  apple.create!(record_params)

write apple id 7 file

indexes = [:id, :title, :desc] record = apple.find(7) to_save = indexes.map{|i| record.send i}  handle = file.open("apple.record","w") handle.write(to_save.join("\n")) handle.close

beware escape linebreaks in data if there possible..

anyway easier use yaml:

#write first apple file handle = file.open("apple.record", "w") handle = apple.first.to_yaml handle.close  #read file new record record_params = yaml.load file.read("apple.record") apple.create!(record_params)

all worked in rails 3, remember, saving id well, therefore saving , loading cause id change, because record given id existed.

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
