Installation hangs on partitioning step on 15.04 x64

Question

I am facing problem in getting values from rendered data in component that is already outputted on page render. What I need to do is, when someone types in data into text field, it should send it to database but taking that fields data from runtime data.

Currently, when I type something, it says undefined field etc. This is not form data but a data that need to be update from text field. So, if user write some xyz in text field, we need to update that data according to the id associated to that field.

I am not able to get data into: console.log(Id, projectId, userId, date, e.target.value) I have used reduce method that serves the purpose but now I have another use case.

I dont want to set hidden fields as its not the right approach.

The problem is that when someone type data in text field, I need to get that text field data and associated id and respective data from it and pass it ti ajax call.

I need to send that data with ajax but as soon as I type something, it says undefined. I can easily get data from projects array but its of no use to me. I think array reduce method is not good for my use case.

Here is project array:

data = [

Solution 1

So, I have good and bad news..

The good news is that I solved, the bad one is that I don't know how I did..

I will write down what I remember in order to be as much useful as I can.

I burnt also a dvd to see if the problem was my usb pen, but it turned out also the dvd had the same problem.

So I booted again with my usb. Until that, I always created and choose the partitions where install ubuntu manually. I thought to give a try with some automatic procedural.

I have a 256GB ssd so partitioned, 100GB to win, 1GB swap and the rest to a ext4 partition. I already had installed win8.1 on one single partition (no system reserved small partition). So I imagined I could install Ubuntu on the ext4 partition by choosing "install ubuntu along windows", but I was wrong, once I clicked this, I had the choise to distribute my space outside win partition to two additional partitions, one for data (photo, documents, music, video, etc) and another for ubuntu itself.

So I clicked back, I chose the second one, "format the whole hd and install only ubuntu" but just for playing with the menu and check out if there were other options, I didn't go further than the confirmation menu and then I went back.

I tried once again the "manual choise", I set up my ex4 partition by selecting the format option and the / mount point, then I confirmed and then when the bottoms went grey, I tried to play a little with the keyboard, especially pressing randomly the arrows keys.

It accessed the following menu, I couldn't believe that..

Anyway, if this last time would have failed too, I was going to install it on the ssd through one of my laptop as last chance before downgrading to 14.10 and then upgrade.

I am sorry I can't give a rational explanation to this, but it worked, I wish anyone with my same problem to solve it too, good luck with that!

Solution 2

Had the some problem.

My solution was to Try Ubuntu, then open GParted Partition Editor, format the previous Ubuntu partition and then install worked fine!

I had this problem and I went to check the console (Ctrl+Alt+1) and there were many errors on /dev/sda... it was an old, inactive computer, and I believe the controller might have deteriorated.

I think you need to provide more details. What do you mean by "when I type something, it says undefined field?" Are you getting an error? If so, what's the exact error? Your code references variables like h, but that's not provided so we don't know what it is.

[LearningROR]

@Jacob I have added data and explanations as well. Does that work please?

[Jacob]

The very first line of code I'm looking at, const found = h.project_times... references a variable h which is still not defined in your code description. Is h one of the projects in your project array? Is daysNumber a return value from getDaysNumber?

[LearningROR]

Yes that right dayNumber get 1 to 30 values from getDaysNumber

[LearningROR]

I am not getting any error but I need to check which field was clicked and updated so i must get the id of that field and update it in database. does that make sense?

[LearningROR]

But the thing is that If I do console.log(h.projectno, h.project_id, h.user_id, e.target.value)} it works fine. I need to get data from daysNumber.reduce thing. So you are right but its not an obvious issue.

[Jacob]

It's not clear what your code is trying to do; what is your expected behavior if there is no matching project time for the day of month?

[LearningROR]

If there is no time match, I need to update that record using text field and I just need to check which text field was being update and then upon that i need to send id, project_id from project_times array to database.

[LearningROR]

You understood correctly what my code is doing, but the problem is that, when there is no matching for hours found, i need to update the hour for that day in the database. So i clicked the text field and write something and i can get its data in functions but i am unable to get the ids and other thing so i can see which records needs updation of hours based on id. does tht make sense?

[Jacob]

As in inserting a new object in project_times?

[LearningROR]

const Id = found && found["id"]; I want this in my function. Did you get it?

[Jacob]

Tried to explain things for you. I'm still vague on what you're getting stuck on, but hopefully this'll help.

[LearningROR]

Thanks a lot for your time on it. It didn't solve my problem but gonna accept it as answer for your efforts. :) As I am not using hooks in my project.
