I am quite new to Rails, and I need to work on a report generating plugin using Rails and Highcharts for the output. My main issue is that my user is meant to be able to define a time range using a jQuery datepicker. How can I get the highcharts graph on the x axis to reflect the time range based on the users selection, and how do I tie it to the other fields in the rails model.
Eg. If I have a table with a created_by field which the user is supposed to pick his to and from dates from... and the table also has user_id and the users select a specific language for each application. I want the graph to show for each day the count of the different languages different users selected during their application.
Hope my question is clear enough. Thanks

I am trying to scrape a website for financials of Indian companies as a side project & put it in Google Sheets using XPATH
Link: https://ticker.finology.in/company/AFFLE
I am able to extract data from elements that have a specific id like cash, net debt, etc. however I am stuck with extracting data for labels like Sales Growth.
tried
Copying the full xpath from console, //*[#id="mainContent_updAddRatios"]/div[13]/p/span - this works, however, i am reliable on the index of the div (13) and that may change for different companies, hence i am unable to automate it.
Please assist with a scalable solution
PS: I am a Product Manager with basic coding expertise as I was a developer few years ago.
At some point you need to "hardcode" something unless you have some other means of mapping the content of the page to your spreadsheet. In your example you appear to be targeting "Sales Growth" percentage. If you are not comfortable hardcoding the index of the div (13), you could identify it by the id of the "Sales Growth" label which is mainContent_lblSalesGrowthorCasa.
For example, change your
//*[#id="mainContent_updAddRatios"]/div[13]/p/span
to:
//*[#id = "mainContent_updAddRatios"]/div[.//span/#id = "mainContent_lblSalesGrowthorCasa"]/p/span
which is selecting the div based on the div containing a span with id="mainContent_lblSalesGrowthorCasa". Ultimately, whether you "hardcode" the exact index of the div or "hardcode" the ids of the nodes, you are still embedding assumptions regarding the structure of page.
Thanks #david, that helped.
Two questions
What if the structure of the page would change? Example: If the website decided to remove the p tag then would my sheet fail? How do we avoid failure in such cases?
Also, since every id is unique, the probability of that getting changed is lesser than the index being changed. Correct me, if I am wrong?
What do we do when the elements don't have an id like Profit Growth, RoE, RoCE etc
Good day to everyone! Hope all is well!
I am looking to run an update query or a group of queries that looks at my Date_Start and Date_End to determine if the Units (quantity of the respective record) fall in my defined current quarter 1/2/3/4 from another table (this table is a master table I’m using to provide the dates that I need to consider for defining the quarters).
I’ve been able to create queries that do this and then join them together to basically display the units out by quarter based on their respective start/end dates. The problem I am running into is this process takes a decent amount of time for the queries to populate that will drastically effect other processes down the line.
Thus we get to my desire. I am trying to no avail to create an update query that will update the quarter fields in my table based off of the queries I built to determine if the records start/end date fall in the respective quarter. I figure that running this update when records change will be an ok run time vs when I’m running reports or running an email script for the reports.
I have tried pulling in the table and query, joining them as equal on ID (the query pulls in the table's IDs), and selecting my field “CQ1” from the table, and setting the Update ether the respective field from the table or the query (which is the same as the field in the table).
All I get are the current values of the field in the data sheet view and an error of “Operation must use an updateable query.”
I have even tried placing a zero to see if that would do it with no luck. I have verified that all the fields are the same data type.
What am I doing wrong? Thanks!
Apologies to everyone.....I think my conscious brain was trying to overly complicate the process and while talking to a buddy about my issue distractedly created a new update query that worked. It all tied down to that I forgot to put a criteria on my quarter filed of is not null I believe. Thanks for anyone that has read this and is responding while I’m typing this or for those of you formulating a response.
I use Google Forms regularly at work, and I think they are awesome, especially since I am a total newbie with coding. With a few good plugins for Forms and Sheets, I am able to generate contracts, invoices, and so on very easily, based on document templates.
To keep it short, here is my request:
I have a form, where I input the customer's details, and upon submission, an addon generates a gdoc, based on a template. Al working great so far. My problem is that we are generating many different documents for a single customer, so it becomes a repetitive and very time-consuming task, considering that I have 15-20 different input fields for a customer, plus specific input fields for each different document.
The first input filed in my form is "Customer Name" and I have managed to create a dynamic dropdown list, that takes it's information from a specific column in a Google Sheet.
My request: how could I auto populate specific input fields in my Google Form, so that, based on my dropdown choice, the auto completed information will match the corresponding row present in the Google Sheet.
I have attached 2 images for easier understanding:
You can actually do this with a simple vlookup:
note: I also always wrap my functions with and if statement that checks if there is text in the first field, so try:
pretend that your dynamic customer name is in cell A1:
customer vat formula -
=IF(ISTEXT(A1),VLOOKUP(A1,'Parteneri'!A:C,2,FALSE),)
customer city formula -
=IF(ISTEXT(A1),VLOOKUP(A1,'Parteneri'!A:C,3,FALSE),)
I am developing a Rails application using ActiveScaffold.
The thing is that I need to filter a list of results by a date range.
(SQL equivalent 'BETWEEN ? AND ?')
I know that ActiveScaffold has a feature that already does that, but it has too many options.
(Past, Future, Range, =, ...., Between). In this case, I only need the Between option in that combo.
I tried overriding the field using the Helper, but the closest I got was to display 3 different combos (one for year, one for month, one for day).
Is there any way to override Active Scaffold so that only displays the "Between" option?
EDIT
Active Scaffold already does the search part well.
I am trying to change the visual part so it doesn't display so many options.
EDIT 2
The calendar plugins for rails are dated from 2009 or they aren't under maintenance.
You can use a range as a parameter in AR.
Model.where(:date => from..to)
Also, I'm not sure if ActiveScaffold has something to do with it. Normally, all the tasks like this one can be perfectly solved within plain ActiveRecord.
EDIT:
As it turns out, author also needs to get the user's input for the boundaries.
This is a common task that can be solved with one of the thouhands js plugins for datepickers.
I would recommend you not to stick to ActiveScaffold for that purpose.
Try this simple Jquery datepicker, and it will turn normal text field into that drop-down calendar. You will only need several lines of javascript then.
If you need further advise, just ask.
I have a very large excel spreadsheet that consists of a user name, a location, a date, and some fields of numbers, for example.
User,location,date,value1,value2,value3
Steve,NYC,2012,9,1,3
Steve,NYC,2011,3,3,2
Steve,CA,2011,1,2,0
Michael,CA,2012,10,3,2
Michael,CA,2011,10,2,0
How would I go about organizing a rails site such that one can view all the values for a certain user?
For example,
/users/steve/all
would display all the values in descending order of date where user=steve.
/users/steve/nyc
would display all the values in descending order of date where user=steve and location=nyc.
I think I would need to create a users model and import all the data from the excel into the database, but I'm lost about how to do that.
The application, in essence, would be a simple data visualizer. Maybe I have to separate the database and create a user has_many :locations and locations :belongs_to user, I'm not sure. I want the data to be viewed in all sorts of ways—maybe I want to display all the users from a certain location, or view all the locations of a certain user, etc...
I suggest setting up your model within your rails application first. Then, you can just write a rake task probably similar to this question or you can build it from scratch. There's also a railscast.
If you need to directly import from Excel (e.g. the excel sheets are uploade by a user). You can use one of the following gems to importing data from an Excel Sheet
roo Reads new and old excel format (+others)
spreadsheet Reads and writes old exel format
If you only have this one excel sheet it will be far easier to simply export the data to csv and follow the answers given in the stackoverflow question mentioned above.
As for the second part of your question on how to model your database you already had the right idea.
Easiest is to fully model what your domain looks like and transform the data accordingly.
