Hi,
Here Params I given for understading purpose.this is a model code I
am passing the params[:objects] from controller to model through
object @objects.But,if I give that No one understands that @objects is
getting from the veiw so I given params[:objects] in this post.(For
understanding purpose).
the controller action
def genericCURDoperation
companyid = session[:companyid]
obj = MGenericCurdOperation.new(params[:objects],companyid)
result = obj.genericAction
puts result
end
In my MGenericCurdOperation model
class MGenericCurdOperation
attr_accessor :companyid,:objects
def intialize(xml,companyid)
@objects = xml
@companyid = companyid
end
def genericAction
hash = @objects.to_hash
operation = hash['operation']
if operation == "insert" then
status = saveToDB(hash['record'],companyid)
elsif operation == "update" then
status = UpdateToDB(hash['record'],companyid)
.................
end
return status
end
def saveToDB(record,companyid)
............
end
def UpdateToDB(record,companyid)
hash = record.to_hash
key = hash['key']
if key==nil then
puts " the key not coming thourgh xml"
return nil
end
value = hash[key.to_s]
model = hash['model']
record = model.find(:all,:conditions=>["#{key}=?",value])
#retriving the record from db
updateRecord = model.new(hash['record'])
# record with updated fileds ,consits every filed in the record
except the key value,attribute
updateRecord.TimeUpdate = DateTime.now
# Here whatever the other requirements and conversions added
to the
# updateRecord and also checking the required fields to
be non empty etc;
recordHash = Hash.from_xml(updateRecord.to_xml)
root = recordHash.keys
rootElement = root(0)
if record.update_attributes(recordHash[rootElement.to_s]) then
puts record.to_xml
puts "saved successfully"
redirect_to 'index'
end
end
end
this is my code with some more operations also
