  • A new Rails idea in views and no more controller. maybe better maybe worse, i need help if this is t

    - by Totty
    Hy, I was thinking that all my website will have use of cells, using the known plugin cell for rails, so this is my idea: A table that contains 3 fields: id, view_name and layout. the layout will be a serialized hash. When a request is made, the layout field is requested and then in the view, default layout, will be unserialized the layout var, that looks like this: @layout[:sidecol][:gallery] = {... some params for it...}; @layout[:maincol][:comments] = {..params...}; In the <% #ruby code to render the cells in the @layout[:sidecol] % will be some ruby code that will loop over the @layout[:sidecol] and render all cells in it. the same occurs in the maincol div. What do you think? Positive in my opinion: More modular controller is used only for post easy change of structure easier to implement some kind of traking to see diferences on what layout is better or not. Negative: not found yet

  • How to organize files in a gae python project, in eclipse?

    - by Totty
    Hy! I have my project with pydev and looks like this: ProjectName -src -gaesessions -geo -static_files -app is this ok? I really don't like to have the gaesessions and geo in my root, but their namespace are by root. I would like to have a structure like this: ProjectName -src -python -thirdParty -gaesessions -geo -app -static_files is this possible? or even better would be to make them as a library. this would be the best thing, but how to do this in eclipse and then when deploy my app, to deploy with those files too? thanks

  • Mongoose 3.1.0: Why the callback in the connection.db.dropDatabase(callback) is never called?

    - by Totty
    Code: var connection = mongoose.createConnection('mongodb://localhost:9000/' + databaseName); connection.db.dropDatabase(function(err){ // never reach this point! debugger; console.log(err); console.log('-------------->Dropped database: ' + databaseName); }); If I do connection.open it says that it's already opening and no multiple calls to "open" are supported for the same connection. Even this doesn't work var conn = mongoose.createConnection('mongodb://localhost',databaseName, 9000, {}, function(){ console.log('created'); // is reached conn.db.dropDatabase(callback); // but the callback is not called anyway }); What is the problem? ("mongoose": "3.1.0") thanks

  • Rails: i would need to load a haml file in a class and render in the caller

    - by Totty
    I have this: app/modules/grid_module.rb app/modules/grid.html.haml then in my view: app/views/layouts/default.html.haml I want to make a new instance of the grid_module and render it content. Its content is into the grid.html.haml and this file can only use the instance vars set in the grid_module.rb is this possible to do? (the grid name is just an example, it must be more flexible, to load the html.haml file based on the .rb class) the grid_module must has access to models too* like this: User.find_by_id(4) thanks for help

  • About presenter pattern in rails. is a better way to do it?

    - by Totty
    I have in my model: def presenter @presenter ||= ProfilePresenter.new(self) @presenter end The ProfilePresenter is a class that has methods like, get_link(), get_img_url(size), get_sex(), get_relationship_status() and other methods that have not to do with the model, not even with the controller but is used multiple times in the view. So now i use them by doing this: Profile.presenter.get_link # or Profile.presenter.get_img_url('thumb') # returns the path of the image. is not used to make a db query

    - by Totty

  • I need to generate a string of 7 chars that is based on the id of the row.

    - by Totty
    I need to generate a string of 7 chars that is based on the id of the row. So knowing the id of the image and a secret key, i should get the generated string. the string must contain chars from "a" to "z" and numbers from 0 to 9. I have a dir that contains photos like this dir/p3/i2/s21/thumb.jpg the generated string is p3i2s21, then is used to calculate the path of the image.

  • EDIT: I need to generate a string of 7 chars that is based on the id of the row.

    - by Totty
    EDIT: I need to generate a string of 7 chars that is based on the id of the row. So knowing the id of the image and a secret key, i should get the generated string. the string must contain chars from "a" to "z" and numbers from 0 to 9. I have a dir that contains photos like this dir/p3/i2/s21/thumb.jpg the generated string is p3i2s21, then is used to calculate the path of the image. EDIT: currently im using the id of the image: id = 55 then i modify and i get path = 000000055 then path = "000/000/055" then path = "000/000/055/thumb.jpg" ready to use! now i want something more clever because is easy to track down all the images from a server, because ids are sequencial: 1, 2, 3, 4, 5, 6... so i must think of creating from 55 a string that is 7 char length and will not overlap with other numbers. I can even transform the 55 to 0000055 and from this convert to a 7 char length string using a secret string. then when i got the secret string and the id i want to get back that 7 char length string. Is this possible? i was thinking about hases but they only uses 0-9 and a-e and are more chars.. :s
