We are running a Postgres on [url removed, login to view] (please create your own free database for solving this project). We also have a Google Spreadsheet and we want you to make it so that saving data in that Google Spreadsheet will save data in the postgresql database. I do not want this done by syncronizing every fifth minute, but rather using events that trigger saving in Postgres immediately. Before the saving has completed, then please make the background color of the cell that was updated red, and turn it back to the color that it originally had after the saving has completed. Please do not save all the table every time, just the changed cell.
The column a in the spreadsheet will be equal to the "id" column of the postgresql table.
Please hardcode the mappings of google spreadsheet (GS from now on) columns with postgresql columns. In a test spreadsheet have the columns:
and the create table statement should be:
create table atable (id int primary key, thedate date, thedate_time timestamp(6), the_text varchar(99999))
Please set the validation rules for the columns in the google spreadsheet, and ensure that no values will make your script unable to sync (apart from dates before 1970 and after 2030).
The syncing needs to be within seconds usually.
It should not be possible to add nor delete postgresql rows from the GS.
If you need one, you get a linux server for solving this project. Our preferred programming language is PHP.
Please ensure that editing multiple cells in one go works. Also, ensure that if there are formulas in the cells, then it is the resulting values that get saved in the DB and not the formulas themselves.
Max price for this project is 100$. The reason for this is that there is a proof of concept of this project here: https://docs.google.com/spreadsheets/d/1F5Ss3iy135tL_MyUFK15oB9Qz4JBj2zXU1ybMoMWlAM/edit#gid=0 But if you find anything in that implementation contradicting the above requirements, then please ask me. For example I cannot see that cells with red background ever get a white background again after submitting the query to the server. The server software (to actually update the database) has not been implemented in that proof of concept.
And I need this within 5 days from you starting the project.
To ensure that you have actually read all these requirements, I will only consider bids where I can find your [url removed, login to view] username in this form: [url removed, login to view] You of course need to also submit a bid via Freelancer.com.
