sql - Error 1005 thrown in MySQL -


i'm trying run 5 create tables statements. 3 of them working fine foreign keys i've declared, tables 'generalweather' , 'userreg' throwing error 1005, know has mismatch in foreign keys. i've been looking error, can't find anywhere. wrong 2 create table statements? (my default schema titled "tester")

 create table `coastal` (   `date` varchar(50) not null,   `time` varchar(50) not null default '',   `am/pm` varchar(45) not null,   `location` varchar(50) not null default '',   `tide description` varchar(50) default null,   `estimated swell(ft)` int(11) default null,   `wind speed(mph)` int(11) default null,   `wind direction` varchar(45) default null,   `visibility (%)` varchar(50) default null,   primary key (`date`,`time`,`location`,`am/pm`),    constraint `coastalfk`   foreign key (date, time, location, `am/pm`)   references tester.locations (date, time, location, `am/pm`)   on delete no action   on update no action,    index `datefk_idx` (`date` asc) ,    index `timefk_idx` (`time` asc) ,   index `am/pmfk_idx` (`am/pm` asc) ,    index `locationfk_idx` (`location` asc) );   create table `generalweather` ( `date` varchar(50) not null, `location` varchar(50) not null, `climatedescription` varchar(50) not null default '', `average temperature(f)` int(11) default null, `elevation(ft)` varchar(50) default null, `recommended activity` varchar(50) default null, primary key (`date`,`location`,`climatedescription`),  constraint `generalweatherfk` foreign key (date, location) references tester.locations (date, location) on delete no action on update no action,  index `datefk_idx` (`date` asc) ,  index `locationfk_idx` (`location` asc) );   create table `locations` ( `date` varchar(50) not null default '', `time` varchar(50) not null default '', `am/pm` varchar(45) not null, `location` varchar(50) not null default '', `location type` varchar(50) default null, `temperature (f)` varchar(45) default null, primary key (`date`,`time`,`location`,`am/pm`) );   create table `precipitation` ( `date` varchar(50) not null, `time` varchar(50) not null default '', `am/pm` varchar(45) not null, `location` varchar(50) not null default '', `precipitation chance (%)` text, `wind speed(mph)` int(11) default null, `wind direction` varchar(50) default null, `visibility (%)` varchar(50) default null, `humidity (%)` varchar(50) default null, primary key (`date`,`time`,`am/pm`,`location`), constraint `datefk` foreign key (date, time, location, `am/pm`) references tester.locations (date, time, location, `am/pm`) on delete no action on update no action,  index `datefk_idx` (`date` asc) ,  index `timefk_idx` (`time` asc) , index `am/pmfk_idx` (`am/pm` asc) ,  index `locationfk_idx` (`location` asc) );   create table `userreg` ( `user name` varchar(50) not null default '', `real name` varchar(50) default null, `email address` varchar(50) default 'none on file', `location` varchar(50) not null, primary key (`user name`),  constraint `userregfk` foreign key (`location`) references tester.locations (`location`) on delete no action on update no action,  index `locationfk_idx` (`location` asc) );

there couple of problems. must build locations table before other tables reference it. move 1 top.

then, need matching index every foreign key define. have composite primary key of 

primary key (`date`,`time`,`location`,`am/pm`)

already, of foreign key definitions work. however, need create additional indexes fk definitions don't use full composite pk. due fact both parent , referencing table must have index defined across complete set of columns use foreign key.

# move table definition first create table `locations` (   `date` varchar(50) not null default '',   `time` varchar(50) not null default '',   `am/pm` varchar(45) not null,   `location` varchar(50) not null default '',   `location type` varchar(50) default null,   `temperature (f)` varchar(45) default null,   primary key (`date`,`time`,`location`,`am/pm`),    # added these 2 keys later fk definitions   # referenced generalweatherfk:   index (`date`, `location`),   # referenced userregfk   index (`location`) );

here's whole thing building properly: http://sqlfiddle.com/#!2/d208e

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
