-

I need to create a website that needs to do the following:

  1. Geographic
  2. When a road is selected, show a set of points of interest on that road
  4. Show a set of selected roads on the map / Ol>

    The obstacles are:

    1. Ruby on the rail
    2. Everything in the stack should be open source

      I have a What is the need to see it necessary Work tasks?

      At a glance or OpenstreetMap will only allow you to load maps in a visualizer (this is a collaborative geodatabank Seems like), and at least Openstreetmap's younger brother / visualizer / tool for the OpenLeary version. I've heard Mapfish is a plugin for rail integration, but I do not know what it is. Best wishes to learn the API of your choice!

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' .

I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
